A week long dive trip in the Great Lakes is also on my list of trips to do.
The Straits of Mackinaw and Thunder Bay (Alpena) are about 2 hours driving distance from each other. Both places each have more than enough wrecks to dive in a week. My vote would be combine both places and discuss recommended dives with the dive charter operator.
