Our family of four is planning a trip to Traverse City in mid August. I thought Mackinac Island would be a good side trip. Our boys are ages 3 & 4. I want to stay somewhere on the island where we can walk to most everything without exhausting the kids. The Main Street Inn on-line looks like a nice hotel at a really bargain price. Is it too good to be true? Has anyone stayed there? I figured any decent place would be at least $200/night at peak season. Another important factor is that my husband can't live without air conditioning. Any advice would be greatly appreciated.
