I am trying to organize a family trip to the Dells around Christmas and need help. There will be 11 of us with 5 adults and 6 kids (ages 5 to 17). We are looking at the best and most affordable lodging (keep everyone together or get multiple rooms) and ideas to keep everyone busy besides the waterpark. I have been to the Dells many times in the summer, but never in the winter. Will there be enough to do if we stay a few days? Are any cabin rentals available in the winter months?
