It's a pretty basic hotel, but that's all we were looking for. The breakfast was really good! I loved that the riverwalk was right behind the hotel.

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!

We choose this hotel for its location on the river walk and its convenience. Friendly staff and reasonable rates are another reason.

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.
