Has anyone been to Leelanau county?  Does anyone know anything about Wine Tours?

I was looking into this and thinking that would be a very relaxing day - having someone tote us around to taste wine :)  But I have never done it and know nothing about it.  One of the hotels I was thinking of is in Glen Arbor, right by where these wineries are, so I thought it would be fun.

Any knowledge, tips, or advice is welcome.  Thanks!!
