So FI and I have decided to save a ton of money by honeymooning up north. We took a vacation to St.Ignace last year, and absolutely LOVED the little inn on the beach we stayed at. So we're thinking of spending the first 3-4 nights there, hanging around St. Ignace and going to Mackinaw Island for a day (staying on the island is soooo expensive). From there, we were thinking about maybe going up to Tahquamenon falls for a night or two or three (they have cabins in the state park for $70/night with a minimum of 2 nights). We've never been up there, but it looks really pretty. We were also thinking of perhaps going up to Pictured Rocks? We went there last summer, but were only there for like an hour on our way to Marquette...
So anyway, what do you all think of that? Do you have any suggestions for other destinations near that area? We for sure want to go to St. Ignace and spend a day on Mackinaw, but we're pretty open to the rest. We are outdoorsy type people and just want something relaxing

We'd like to be gone for about a week.
Thanks for any input!
