M.O.
We go to the Dells every year for a Winter Vacation. We rent a Villa at the Wilderness resort and Grandma and Papa come along and everyone has a great time (especially after the kids crash at night and mom and dad can go out since the babysitters came along). The Villa has 2 bedrooms upstairs, a large bathroom with a shower and jacuzzi tub upstairs, a shower bathroom downstairs, a full kitchen and eating/living room area with pullout couch.
The water parks are Fabulous and are great for all ages.
If you stay at the resort hotels you can get great coupons for area attractions and restuarants.
Have FUN!!!
