Friends and I rented a 4-bedroom condo for the weekend and had a blast! There are 2 waterparks, each with body slides, tube slides and a feature ride (the Hurricane and the Cannonbowl). Important to note: Wilderness does not sell passes to the waterparks, so only resort guests are allowed to use them.
Also available: an arcade, laser tag, pottery making, wagon rides and other seasonal activities. A shuttle will take you anywhere you need to go on the resort grounds.
The condo was fully equipped with kitchen utensils, a dishwasher, icemaker, DVD and video, extra towels and pillows. I would recommend bringing extra blankets, however, no one was cold as we had temperature control. There were also 2 fireplaces in the 4 bedroom condo.
It can be pricey compared to other cabin/condo rentals in the Dells, but having the waterparks right there offers a lot of fun.
A llot of families vacation here, so expect many children.
