What I love about this thermal is the amount of choices of pools they have to enjoy your visit. The outdoor pool is the best. I really did not find any pool/ thermal really hot but it was very relaxing and fun day. You can share a changing room if you buy your ticket with that option. Also you can even buy your entrance the same day there but I heard is not recommended. We bought them on line. The place is huge, not too much direction where to go so it’s better explore the place. It was nice to be able to eat at the restaurant, not too bad. We booked this activity our last night in Budapest and it was really relaxing to a tired body.
Yes, you need a towel and flips. We brought ours.
