Would appreciate some help in planning a girl's week away, July 2014. Not interested in taking a bus type tour, but unsure how to proceed. Will be meeting from different cities on the East Coast, so need to know best place to meet, and driving route. (we are all 50ish). Interested in staying 2 nights at the Grand Hotel, but would also like to see Frankenmuth?, Sleeping Bear Park and any other natural sites. Also, if we rent a car, where can it be left for the ferry ride across? Thank you.
