Can I join ESN Sea Battle, if I am not an Erasmus/exchange/international student?

Absolutely, and the same goes for your friends! The one and only criteria is that you have to be at least 18 years old.

Can I travel with my national ID?

Yes, national ID cards issued in the EEA are valid for the cruise. It should state your nationality and be valid for travel within the EEA. This means that a driving licence and other local IDs are not valid. Another option is to use your passport, of course. If you’re from outside of Europe, make sure to also bring your visa/residence permit with you.

Tickets and Payment
How quick do you need to be in order to secure yourself a spot?

Tickets are limited, so we recommend booking as soon as you know that you will be able to join us on this cruise.

Can I buy tickets for my friends?

Absolutely, you can purchase tickets for up to 4 people in one order (depending on cabin type – max 1 entire cabin per order). If you are a bigger group, you can make additional bookings.

Can I book an entire cabin?

Yes, you can! Just add as many tickets as there are beds in the cabin type you selected (i.e, for Warrior you have 4 beds per cabin, so 4 tickets).

My friends already have their ticket, can we all stay in the same cabin?

If your friends have made separate bookings, use our cabin preference form (sent out to all participants) so we can put you in the same cabin. Important note: All of you must have the same cabin type!

My friends booked another cabin type than what I did. Can I change my cabin type to theirs?

We can upgrade your cabin type (to a cabin with the same or higher ticket price), provided the cabin type is still available. Similarly, it is also possible to downgrade your cabin, note however that the price difference will not be refunded. Contact us at support@seabattle.se, and we will help you with this.

My group is staying in multiple cabins. Can you put us in cabins that are next to each other?

Unfortunately, this is not possible. 

I have a ticket for Sea Battle but can’t make it any more. Can I transfer my ticket to someone else?

Yes, transferring tickets (name changes) is possible for free until 14 days before departure, and later for a fee. Read more here.

My payment failed, how can I fix that?

Make sure you have activated online payments and international payments with your card provider. If the issue persists, contact us at support@seabattle.se

My order status is “Pending”, what does that mean?

There is an outstanding amount to be paid for your order. This is usually due a failed payment. Please go to your order page (find the link in the “Order placed” email), and attempt the payment again. If the issue persists, contact us at support@seabattle.se

Do I need a credit card to purchase a ticket?

We accept all common credit and debit cards (Visa, Mastercard, AMEX etc).

I did not get a confirmation email, what now?

Please double check that the email is not in your spam folder. If you still can’t find it, you might have typed your email address incorrectly. Contact us at support@seabattle.se, and we can update the email address of your order.

I forgot to book my ticket with the discount, is it possible to still get the discount afterwards?

The ESNcard discount must be applied when you place the order. We can’t add it retroactively.

I am not 18 years old yet but will be right before the event, is it possible for me to buy the tickets now?

Of course, you just have to be 18 years old at the time of the event.

My identity document (ID) will expire before the cruise, but I’m going to get a new one before the cruise starts. Can I still book a ticket now?

Yes, just remember to keep in mind delivery times of your ID, as a valid ID is required for travel. Update the ID details on your booking as soon as you receive your new ID.

How can I get the ESNcard discount?

It’s easy – just follow these 3 steps:

  1. Buy your ESNcard from your local ESN section – Find your nearest one here*
  2. Register your ESNcard on ESNcard.org
  3. Book your discounted Sea Battle ticket by entering your ESNcard number during checkout

It may take up to 4 hours after registering your ESNcard until it’s valid in our system.

*Please note, ESNcard eligibility requirements applies. All international students or interns are eligible. Local students can get an ESNcard if they are an active or alumni volunteer for ESN, or if they are actively part of a buddy program for international students.

Where can I find my ESNcard number?

The ESNcard number is printed on the front side of your physical ESNcard. Make sure to type it correctly, both when registering your card and when booking your Sea Battle ticket.

Why can’t I use my ESNcard to book tickets for all my friends?

We offer a discounted price for ESNcard holders since they are supporting the Erasmus Student Network through their membership. This membership is personal, and therefore the discount can only be applied to one ticket.

I’m getting an error related to my ESNcard during checkout. What am I doing wrong?

First, check the error message for details. You might not have completed the registration process on esncard.org. If you have trouble logging in on this site, check your emails (and spam folder), often it is due to you not having verified your email address.

It may also take up to 4 hours until the registration of your ESNcard shows up in our systems. If the issue persists after this, contact us at support@seabattle.se.

Do I need to have the ESNcard to be able to participate in the event?

Of course not – We are all for social inclusion, and thus our event is open for everyone. ESNcard holders can buy cruise tickets and pre-event tickets at a discount, but apart from that, non-ESNcard holders can also enjoy the very same once-in-a-lifetime experience that ESN Sea Battle is!

Is there a refund policy?

We can refund your ticket up to 14 days before the departure date. Contact us at support@seabattle.se if you’d like to cancel your ticket.

A cancellation fee applies according to when you request a cancellation:

  • > 60 days before departure: 10% of your ticket

Can I sell or transfer my ticket to someone else if I decide not to go?

Yes! You can transfer your ticket up until departure day. A ticket transfer fee may apply according to when you request the ticket transfer:

  • > 14 days before departure: Free
  • > 7 days before departure: 200 SEK

Late ticket transfers/name changes (<= 14 days before departure) can be requested by contacting us at support@seabattle.se. Please note that we cannot change the cabin preferences in case of a late ticket transfer.

How do you refund me?

We refund your money to the payment method used for your original purchase. This process can take up to 5-10 business days.

Note: If the refund is done shortly after you placed your order, the refund might instead be processed by cancelling our original charge on your card. In that case, you will not see either the charge, nor the refund, on your card statement.

Activities onboard
I am wondering whether I belong to your target audience. Is it just ”party people” or how does it work?

The programme of ESN Sea Battle is very diverse. With a strong focus on inclusion, we adapt more and more activities each year to create a safe and fun environment for everyone. While, of course, we have themed parties at night, our program also consists of various games, sightseeing tours of Stockholm and Tallinn, challenges and social events throughout the whole time of the journey.

Over the years, we have built a solid reputation as an event that cares about people, their needs and desires, and we hope you will join us to have this unique experience for yourself.

What kind of activities will there be on the boat?

Expect city sightseeing, karaoke, live DJs, treasure hunts, sing-along, dance classes and much more! You will find all the details once our official Programme is released, closer to the departure date.

Safety onboard
What precautions are taken to keep everyone safe onboard?

For the organisers of ESN Sea Battle and all of our volunteers, safety is top of mind. We actively work for a safe environment through our Safe Battle initiative, by which we will have trained volunteers around the ship throughout the evening programme, in addition to security and medical personell from Tallink Silja (our cruise operator).

We are also partnering with Drink More Water to promote a healthy lifestyle and to raise awareness of the risks of binge drinking and the misuse of alcohol. You will find volunteers handing out water and other goodies outside our main venues throughout the night.

Reach out to any of us volunteers or a member of staff if you have any concerns!

When should I arrive in Stockholm?

If you arrive on Sunday 14 April for the pre-event, please be at the Generator Hostel by 13:00 for check-in. The afternoon activities will start shortly thereafter.

On Monday 15 April, please arrive at Värtaterminalen (ferry terminal) latest by 13:00, as check-in will take place then. You will receive further instructions about check-in in our Survival Guide.

Can I stay in Tallinn and not come back to Stockholm?

Yes, you can stay in Tallinn, but please inform a Sea Battle volunteer if you choose to do so.

I am coming from another country or city, is there any transportation available?

Some local ESN sections provide group transportation to and from ESN Sea Battle. Please contact them for details.
