We are going to the Dells the 17th and 18th of June. Our son and girlfriend and daughter and boyfriend all in 20's. We don't have a lot of time, so we want to make the best of the time we have. Can you suggest a couple of must see/do things and a couple of great eateries. We are staying at the Great Wolf Lodge. Thank you so much. We haven't been to the Dells for many years. Our children were in grade school.
