The indoor waterpark at Schlitterbahn was perfect. Of course you may not get the exotic water slides. For a fun family trip and something to do in the winter, it was perfect. My family stayed at the resort, Usually at resorts you don't get the free breakfast. They have many selections you can choose from here. I was quite fond of the room key. It was on a bracelet that had a magnetic waterproof strip. I will definitly come back. Yes, I have been to many indoor water parks. This is a cute small indoor water park. Yes, the pools are heated now in the winter, They just opened the resort this Summer. It had everything for the family. You can bring your own sandwiches and drinks. They also provide life jackets for the kids.
