Take loads of money for the drinks!
i went there earlier this year in Febraruy.
Get a northern lights app on your phone. if it’s looking strong the cooach trips out to goa nd see them are expensive for what they are but worth it to get out of the ‘city’ and get super clear view
Burger bar/ music memoriablia place is good value for food.
brewery / polar bar could have been good, but we only got there in time for one.
Tourist information there is good for booking anything/ seeing options around.
There happened to be the local northern travelling reindeer farmers festival going on that week too which was very cool but unlikley to be on again.
Take a walk over the very cold bridge to see the super modern church.
The boat ride was nice, but you did just effecveliy tour the island and not a lot more,
