Great room facing river from 6th floor Very nice helpful staff. The check-in area is not a good representation of the hotel. It needs a remodel - it’s dark. I understand the “ship” theme but it isn’t appealing.

The resort is average as far as cleanliness and rooms go. I appreciate the location convenience, the riverfront path and view, Tony Romas, and the water park when grandkids are with us. Parking is convenient and the staff is always friendly and helpful.

The staff was very nice! Tony Roma’s was not as nice, they refused to seat us because we had kids and the meal deal for them and told us take out only and to use the community area around the corner to eat even though we were ordering food on top of the family meal deal. They then took forever and ignored us when we were right at the counter. The grand water park was fun and the hotel was clean with lots of activities. The breakfast wasn’t kid friendly

We have stayed here several times in the past. The rooms need upgrading. The phone was completely dead, the bathroom door squeaked loudly (think during the night), and the tub/shower had no safety bars but ironically, an emergency cord to pull if you fell. The continental breakfast was lousy and after the first night we never returned.

We were in Dubuque on a Monday night. We went to the casino to have dinner and not one of the dining options was open. We then tried to find dining outside of the casino and the whole town appeared to be closed down after 6:00.
