Southern Wisconsin, Wisconsin hotel rooms at the GrandStay

"Loved location and pool"

"Positives : We went during the off season and the hotel was pretty much to ourselves same with the water park and arcade. Which was perfect for us and our 1 year old . The room has a whirpool which was also a plus , very spacious for the little one to wander . The waterpark was definitely run down and paint chipping . Water was cold besides the hot tub. You can tell that at some point this hotel was in its prime but in 2026 definitely needs some work done and lots of maintenance. A lot of the amenities did not work- our tv and remote were not working , laundry was not working , we had to plug the fridge and microwave in ourselves . Overall we did enjoy it mostly because we got all the space to ourselves . "

"Es un buen lugar para que los niños se diviertan, disfrutan de las instalaciones con suficiente seguridad. "

"Worth it!!!"

"Restaurant hours are sporadic and not always available, for that reason we never had breakfast at the restaurant. Restaurant was open for dinner 2 of the 4 nights we were there. We did have dinner Monday night and the dinner was pretty good. "

"Rooms were pretty clean. Beds were comfortable. Nice to have a full kitchen and washer/dryer in the unit."

"Very clean and comfortable. Staff were helpful and rapid in any needs I had. Check out the pool on 23rd floor! Amazing view and the pool is very nice. "

"COCKROACHS. DON’T stay here!!!! Tell other families not to. This place is a disaster. Building 10 cockroach infestation. I emailed a picture of the cockroach to management and requested a refund. Checked out early and hotel management asked me to sign a corrupt agreement that says customer won’t disclose.l in exchange for a refund that was equivalent to one night stay and a credit to come back to this cockroach party. I disputed the charge to my credit card company and will file a complaint to state health department inspections and appeals, hotel licensure, better business bureau, and the WI Attorney General’s Office. Mt. Olympus knowingly exposes families to health risks associated with cockroach infestations. "

"Family friendly "
