Travel Planning

My husband and I will be taking our daughter to a camp in Michigan this summer, and I'm working on planning the trip.  After we drop her off, I want to stay and see some of the state.  I've never been, and why would I be in a hurry to get back to Dallas in the summer??  These photos are of The Grand Hotel, and are in Carleton Varney's book Mr. Color.  The Grand Hotel is on Mackinac Island in Michigan and opened in 1887.  Carleton Varney was hired in the 60s to redesign the interior.  

Obviously, this is on my list, and it's not very far from the camp.  Do any of you have any suggestions for me?
