Hi, No extra cost once inside unless you decide to get something from the giftshop (like €3 for a can of Angry Bird coke I dont think so! lol) or have a coffee in the reasonable priced Holiday Club Saariselka next door. The prices are:- Tickets €19 Next day ticket €12 (you need to keep the braclet on from previous day) Under 4s go free However, If you stay at the Holiday Club Saariselka right next door and travel with Thomson or Inghams, you may get either 20 or 25% off like we did last December. We travelled with Thomsons to the Holiday Club and spent time on our last day there. We was not aware of the discount until the member of staff asked if we were and applied the discount. If you are on a tight budget, try to use any spare luggage allowance for snacks to take over there as the Supermarket we encountered was very pricey on that front, even more expensive than souvenier shops selling the exact same gift! We also saved a huge proportion on excursions by booking direct with Husky and Co (across the road from the Hotel & Angry Birds) with combo deals and paying cash and getting an extra 10% off. If you need any other cash saving tips please feel free to message me.
