I loved pulling into the grand motel and feeling very excited for our stay. The staff was warm and inviting, very knowledgable front desk staff. The waterpark was also fantastic! What I didnt like, cleaning staff cursed in front of my children and a housekeeper on the 3rd floor wreaked of marajuana, my hallway smelled like vomit, half the arcade games were out of order, limited, stale and tasteless breakfast options. There were also huge swarms of Mayflies all over the riverwalk, which is great for the ecosystem, however recommending bug soray should be added to suggestions for stay.

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.

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 bed was really comfy. They accommodated me with the request that I wanted up on the top floor. Great check in. Unfortunately there’s no way to skip around the fact that for an hour and 20 minutes the fire alarm went off at least 11 to 12 times. After walking down the stairs over three times with rheumatoid arthritis I was in quite a bit of pain and just quit going down. The firetrucks didn’t even show up until many many had gone off. The fire alarm was deafening and at a very high decimal so kind of ruined the evening otherwise the visit would’ve been excellent.
