We spent our Leap Day weekend in northern Michigan and staying at McGuire's Resort was a great get away.
McGuire's has it all. 27 holes of golf, 2 restaurants, tennis, indoor pool area, 10 km of cross country ski trails, 3 km of lighted ski trails, snowmobile trail head and horse drawn sleigh rides on Saturday nights.
Being here in the winter, I can not tell you about the golf conditions, but if they are anything like the rest of the resort, I am sure they are great. The room accommodations vary in size and age but all are worth the price. Curly McGuire opened the resort in 1949 and various buildings have been added over the years, so there are some areas that are newer than others.
If you are looking for a great get away, I highly recommend McGuire's.
