So I go to school in Milwaukee and figured since I was bored I would go use my free Keylime Cove pass. I walked in and said "this is it"? The place was dead (3 people in the wave pool, 2 people in the lazy river, 1 person on the slides, and a few kids on the play structure.
The place was actually pretty nice but it really is geared to family's with little kids. They had a toilet bowl tube slide, 2 body slides, and 2 other tube slides. The layout is a pain though because when you get off the slide you have to walk so far to get back to the steps. They also had the lazy river, the little wave pool, and the play ground area. We rode everything in about 15 mins. Then we just spent the rest of the time in the hot tub and left after about an hour.
Now, if you had a group of friends and were bored in the dead of winter it wouldn't be that bad of a place to go. Although for the price, you are better off spending the money to drive to the dells.
