you get a bracelet with a chip and you pay drinks and food and lock your locker with that and when you leave you have to pay what you bought. the floors are very hot so but there are sprinklers
very well organised park with a LOT of rafts which is good because you don't have to wait to get a raft. we went on july 4th, arrived at 10 and left at 6. we never had to wait longer than 20 minutes
We brought our own food and only bought some complementary drinks. The cashless payment with a bracelet is very convinient unless you lose the bracelet and have to pay 500 Kuna.
