Property was great , just had a little inconvenience with noisy people next door and staff members taking over an hour to take care of the problem in the middle of the night and still lying about them fixing it

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 stayed here after a concert. Brittany at the front desk was AMAZING. She was accommodating, personal, and helpful. The hotel is old and could use a major update.

Decent newer facility however rooms had quite a bit of damage and were beat up. Carpet had holes. Door had to be forced shut like hinges were bent. Corners and behind furniture was dusty. The view however was immaculate.

Close to the river. I liked the walking area. I wish it was longer for my run and walk, but it's lovely and well maintained. It would be a great place to bring our grandchildren!

Clean room, friendly helpful staff. No grab bars in the shower. Waterpark had enough variety for little ones and older kids but not so big that you had a hard keeping track of where they are.

Lack of emergency protocol

The clock on nightstand was dusty and sticky. Fire alarm in hotel came on and everyone were evacuated from hotel. Building has no P/A system to direct people.,Kids crying and parents confused. No employeees to help. We had to help other families with little kids. Took about 15-20 minutes to get out of building and still no fire department. Finally they show up and leave but no one gave us any information or told us ok to return to rooms. When we asked why so long for fire department to come they said alarm not connected directly to department and employee had to make the call after they figured out what caused the alarm
