The hotel is a little outdated but still clean and comfortable. Every staff member we encountered was amazing! Friendly, helpful and very accommodating. The arcade needs some work with half the games out but the pool and all its features were awesome and they had a cool kids zone full of activities. Overall it was a great stay and we would definitely go again!

Waterpark was the perfect for our 5 year old son. Plenty for him to be entertained with and small enough for us to keep an eye on him. Also the staff was great to work with.

The water park was a lot of fun. They have several arcade games at this hotel. The free breakfast on the second floor was great. The only negative thing about breakfast was, they didn’t have waffles. My kids love waffles. I personally enjoyed the scrambled eggs, sausage, potatoes, biscuits & gravy. They also had cereal & milk. The rooms were nice and spacious. Gorgeous view of the river from the 6th floor. They cleaning staff were amazing, helpful, and super friendly.

Our room was overall clean with the exception of the coffee area. Kids club was fun! Waterpark is very dated and TONS of rust but still fun. Kids water area was freezing but the pool areas were average water temp. Keep in mind the walls btwn rooms are thin, you can hear every conversation that goes on 😬
