Liked: Staff & service

Room fixtures were below average. The desk chair was very low grade (metal frame with a cloth seat, non-adjustable) and I was there for work in the area (not entertainment), so that mattered to me. Tony Roma's service was very poor as numerous employees completely ignored me while they walked by and/or clearly saw me standing at the host/hostess counter for what seemed like well over 10-15 minutes. Their customer service was simply bad--really bad. I wouldn't say my stay was a horrible experience, but it was definitely disappointing. Sorry, I'm just providing an honest assessment from my perspective.

The staff was very friendly and helpful, but everything was a little worn down, a little broken. Many of the machines in the arcade didn’t work. The elevator button did not light up. Lots of chipped paint. The management needs to invest in a refurbishment.

Great location on the river and having the Mississippi River Museum and a nice wine bar within walking distance. Everything about the hotel and water park is getting dated and worn out. The on-site restaurant has average food at best. Regardless, the kids don't notice these things and enjoyed the trip.

We liked the access to the downtown and the outside was attractive. Unfortunately, the walls were paper thin and it was noisy all night. We had to address our neighbors at 3:30 am because of the loud talking, playing and tv. There were at least four kids that I saw in the room, and two "adults" who didn't have any concept of hotel etiquette. The surfaces in the room were clean, but not the look (yellowing, peeling wallpaper, and mold in the washroom; with a drippy sink and shower). We stayed here two years ago and liked it, but we both felt that it had gone significantly downhill from our previous stay. Sadly (because we like the location), we will not be back.

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.

Housekeeping was below average. Our room had a used coffee pod, pull out bed was not made and springs were poking through the mattress. The head of housekeeping told the front desk the mattress had been switched out and it had not been switched out. The housekeeper was over heard telling staff that they would switch it out tomorrow.The Resort was full and had only 1 elevator working but guests were allowed to use service elevator. The hair dryer in the room did not work. Family members staying in a sweet had a jacuzzi tub that had an out of order sign posted. That was basically our stay, everything was out of service. I will not be returning or staying at any of their facilities in the future.
