KeyLime Cove Waterpark Resort in Gurnee. Rooms start at $119 a night for up to six people with dates into May.
Kids of all ages will find something to do here. The indoor facility—which is kept at a balmy 84 degrees—houses two 500-foot water slides, a wave pool, and the interactive Toukie’s Big Deluge aquatic playground for kids. KeyLime Cove is a conveniently cashless resort. Upon check-in, you’ll receive a high-tech wristband that also functions as your room key, waterpark ticket, and credit card for anything and everything at the resort.
Rates start at $279 for a 3- or 4-Night Stay for Up to Six at Mirror Lake & Tamarack Resort in Wisconsin Dells. Combine Up to 12 Nights.
Full kitchens, crackling fireplaces, and natural-wood furnishings add touches of home to the guest rooms. Jetted tubs make for nice spots to unwind or stow the family alligators. You don’t need to head to the dells to stay occupied. There are onsite swimming pools—both indoor and outdoor—as well as basketball and tennis courts. Tamarack’s staff arranges seasonal activities ranging from cookie decorating to wine-and-cheese socials. In warmer months, guests can barbecue on the outdoor grill or go horseback riding and mountain biking along the shores of the lake.
