I agree with most people, Oshtemo is a must play, then coldbrooke, then I would suggest the south course at meijer broadway (2 18 hole courses in Three Rivers). If you have time to hit all those and want more I would suggest Robert Morris. Knollwood is really fun even though most holes are very short and ace-able so if you're looking to play like a 30 or 45 minute round, its perfect. If you can travel, definitely head 20 minutes up to wayland to play Blue Gill DGC if you can get a hold of Joe Gill (invite only). He's really cool though and will help you out if possible and to me its worth playing over all the rest of the courses for the area. Awesome day trip! If you're in town for a while, be sure to drive 2 hrs out to Flip City (Usually rated among top 3 courses worldwide! It's epic.
