After driving past it on many trips, we finally decided to stay at the Great Wolf Lodge in Wisconsin. The place is definitely geared toward the cubs and pups, but we quite like our room here. It is very off-season, so they gave us an awesome deal on a room with a jacuzzi and fireplace. Although I uploaded my picture last night, I didn't post it here because I was too busy soaking away the day's long drive.
Unfortunately today's drive will be even longer, but nothing we can't handle IMO.
