Excellent riverfront location! Lots to do within walking distance. Hotel itself is definitely due for an upgrade. Waterpark is nice but small and crowded. Felt unsafe in there our last day due to the amount of people! Breakfast was your typical hotel breakfast and was always kept full.

The big bummer was that the waterpark was closed the whole length of our stay. So we didn’t get to use that at all. The breakfast wasn’t that great in our opinion. The room was good and the view is always amazing. Great location!

The room we stayed in was dated but clean. I have no clue why you would have carpeting in a waterpark hotel (or hotel in general), but it was maintained. The waterpark could use a little TLC, but overall the staff was helpful and courteous.

We had a great weekend stay! The staff was friendly, welcoming, and always willing to help. The waterpark was a lot of fun and kept everyone entertained, making it a perfect place for families to spend the weekend together. While the waterpark could definitely use a fresh coat of paint and some cosmetic updates, it was clean and served its purpose well. Overall, it’s a great spot to meet up with family and make fun memories together
