Location was perfect. Was in town for a concert and couldn’t have picked a better location. Staff was very attentive and friendly. Only draw back was they didn’t have a shuttle. But that’s minimal. Didn’t attend the waterpark due to timing. Have heard many positive remarks about the facility and waterpark.

Kids had a blast

The front desk, housekeeping, and lifeguard staff were all very friendly and prompt. The staff at the snack shop inside the water park left multiple times for an undetermined amount of time (including around lunch time) and put up a cardboard sign that read "Be right back." Once they were back they were rude and didn't provide what I ordered. The water park is run down and needs a lot of TLC but my kids (ages 3 and 7) still had a blast. I found a dead cockroach in the hot tub. At the attached restaurant the food was good but service was very slow. The gym was very disappointing -- it was clean but there is no treadmill, hardly any dumbbells (only had one 5#, 1 20#, and a set of 35/40/45/50), and half the attachments on the multiuse machine were broken.

If you are prepared for lots of kids, this resort is wonderful! The staff went above and beyond for our comforts Even with the hotel full, our room was peaceful and quiet. The surrounding area has lots to offer for adults as well. And, you can’t beat a dinner of Tony Roma’s ribs while on the patio overlooking the Mighty Mississippi River!
