I want to pass along some advice, or maybe a word of warning. I took one of my nieces and my nephew up to Mackinaw last week, and boy did the price of food come as a shock! I think they are trying to keep up with Disney! 3 burgers (2 with fries which were an up-charge from kettle chips) and 3 pops came to $60 at a not so fancy "saloon". Lunch on the island, another $60.
And here is something funny that happened that you over the age 40 or so will understand: We went to get gas, with my nephew driving. The gas tank is on my side of the car. Gas guy knocks on my window and asks what type of gas we want. Another guy starts to clean off the windshield. Both dear nephew and dear niece looked totally confused and bewildered! Apparently they still have a full service gas station up in Mackinaw. Neither of them had ever used one before, and the whole "what the heck is going on here" vibe made me laugh!

I had to explain that that is how we got gas, back in the day.
