I don’t typically leave bad reviews, but it is warranted in this case. This was, hands down, the worst stay I’ve ever experienced anywhere. I can tolerate old & outdated, but not the stink. The musty, mildewy odor permeated everything-carpet, bedding, & everything we brought with us, so when we got home everything that could be laundered had to be. Our bags are still outside to air out. The bathroom facilities had been updated & looked decent, but there was a sewer gas smell that occasionally occurred. It was so bad during the night we had to open the window. We considered loading up & leaving right then, but I didn’t want to wake the kids & I wanted to talk to the property owner about it. Pretty sure she knew, because when we checked in, the window was open & a/c & fridge were unplugged even tho it was a hot muggy day. We should have known, because there was a sign behind the check-in desk that stated no refunds after check-in, so I’m guessing they’ve had that request often. We did actually look for somewhere else to stay but availability in the Dells in summer without prior reservations are difficult to come by. The one redeeming quality was the outdoor pool, which was decent & we used a lot because nobody wanted to be in the room because of the smell.
