Everything was pretty dated. The waterpark was rough. Lots of flooring worn and crumbling, rusty play structures. The continental breakfast options were okay, but the plates/bowls were all styrofoam. We weren’t given info on WiFi or checkout procedures, but the staff was very friendly and willing to help.

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.
