OK Rob. I just talked to my Pops, who is up in Munds Park right now, and he said that you don't have to be a member, but someone in your group does. That might be a problem. The rates are much cheaper that expected. For non-members, it's around $55 on the weekends, and around $45 during the week (and that includes a cart). It's cheaper if you want to walk. If finding someone to golf with, that's a member, is a problem, there is always Beaver Creek Golf Resort(which I think was already mentioned), that is about 20 miles south of Munds Park (on the north end of Camp Verde). It is cheaper than Munds Park, and anyone can golf there.
Good luck, and maybe I'll see you at camp.
