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.

They had hidden fees and the price was way too high . We didn’t get a pass to the water park . So it could’ve been way cheaper. We never go there again.

Good stay but could be better.

Staff were great. Our room was clean. Bathtub did not drain well. No complimentary shampoo. Continental Breakfast was ok. OJ was watered down. Toasted didn’t work well. Hotel needs some updating.

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.
