Kalahari has both great indoor an outdoor water parks. It also has a movie theatre, indoor theme park (including giant ferris wheel), spa, and great restaurants all within the complex.Wilderness has the worlds largest indoor and outdoor water park area. They also have restaurants with in walking distance, arcades, pottery painting, and a new zip-line.Chula Vista has had major renovations over the past few years. They have a great selection of restaurants, water parks, and family activities.Activities not to be missed-Dells Duck Boat Rides, Noah s Ark, shopping downtown, and surrounding small towns. Most hotels offer great coupons book too.
The 3 big ones / most popular with significant indoor water parks are: Kalahari, Great Wolf and Wilderness. All are great for families. Probably a great time to go to the Dells, won t be crowded yet unless you are considering Memeorial Day.
Kalahari is a good place to stay. I have heard that their customer service is very good.
