If you're going to head to Northern Michigan, which by the way Greywalls is in the U.P. which is 4.5 hours north of Traverse City, then my suggestions would be Kinglsey, Greywalls, Arcadia, Forest Dunes, Tullymore. Obviously Crystal Downs, if you have some connection would top that list. If you're flying into like Lansing area: Eagle Eye, Lost Dunes and Dunes Club...Tullymore.....are great options within about 2 hours from Lansing.
