This property was in a great location. We visited the River Museum and Aquarium, which is right next door. Justin, at check in, was very friendly and helpful. He gave us some great recommendations for places to eat and have a beverage. We greatly enjoyed 7 Hilla Brewing Company and the famous hamburger at Paul's Tavern. We also enjoyed the hearty breakfast at Tony Roma's with the incredible view of the river.

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!

Location was great. Room was clean but it was just a basic room no frills. Breakfast was a disappointment. The woman when we checked out was to busy on the phone with personal stuff to help us and after awhile someone else checked us out. Not sure if we'll stay here again.
