Hi...I am planing on completing a road trip where I head through Michigan up to the upper pennisula and then back down through Wisconsin ending in Chicago. Was looking for a recommendation for a nice resort on Lake Michigan. Would prefer 3 to 4 star, I like boating and hiking but really have no particular requirements. I noticed the Inn at Bay Harbor and the Homestead and they caught my eye...any suggestions would be appreciated...also how much time is needed on Mackinaw Island? Looks like a day trip..no??? Planing on going sometime between May and Sept...
