We will be visiting in July and are trying to figure out how many days to spend at the park. We'll be meeting friends there and would also like to visit Lincoln's Boyhood Home, Santa Claus Village & Museum and anything else right around the area that is of interest. We will be arriving on a Thurs. night and leaving on Sunday early afternoon so that gives us 2.5 days to see everything. Our kids are 8-13 age range. Any insight would be appreciated.
