My best friend and I went with our 5 kids ranging in age from 5-13yrs and we had such a blast!! I mean, if you want to be at one of the huge hotels that have the waterpark and all the attractions right there, this isn't the place for you, but it is much more affordable, only about 10 mins away from those larger places and it's just on a smaller scale.
There is an arcade (a small one, but stil) a pool with a slide, free WiFi, friendly staff, and like I said... only 10-15 mins away from anything else in Wisc Dells that you want to do. I Loved it and would go back there again in a heartbeat.
Only downside was that the walls are paper thin, and you can hear everything!! We had a fan with us so I just ran that at night and it was perfectly fine.
