Having been to other water park resorts, I was uncertain whether the water park area would be appropriate for my teenage kids (12 & 15) or more geared toward younger kids. My daughter (12) experienced both the indoor and outdoor parks and loved them. Surprisingly, my 15-year-old son had just as much fun. I am a big fan of the outdoor water park...not too crowded when we were there (July, Saturday afternoon), access to youth and adult beverages and plenty of seating.
We had pizza delivered from an on-site restaurant and were shocked when our 14" Lotsa Meatsa pizza arrived...IT IS WELL WORTH THE PRICE OF $29. It was closer to an 18" pizza and didn't skimp on toppings. We ordered $4 "side salads" that were dinner platter-sized, with mixed greens!
Resort is a few miles from all the tourist attractions of the Dells...attractions are not in walking distance. This wasn't an issue for us as we were there for a basketball tournament, but if you want to walk to the attractions, this isn't the place for you. That being said, I appreciated it being away from the congestion of the Dells downtown.
The only complaint I have, which is probably typical of hotels with water parks, is that the room was humid/damp. It was improved by running the A/C but I do wish it wasn't so humid.
