Couple things
If you are going to spend the money to drive the 8+ hours to georgian bay, paying for gas, food, the lodging...Why not spend a couple hundred extra to hire a guide to show you the area? Looking at the whole picture that would be a drop in the bucket.
It makes perfect sense to pay a guide on the first day you are there to fish, so the rest of the week you have an idea on what to do and where to go. That guide could make or break your trip. Think about it you might spend half your vaction looking for fish and get a few, or have someone that makes a living on the water show you the pattern that has been happening just days before...
Also make sure you got your ****s in order, you will need them to get back in the states.
Personally I would rather spend a vacation locally fishing, maybe hire a guide or two on more local water. The best part about that is you can sleep in your own bed, and no worries about major issues happening when on your trip. If I had a week to just go musky fishing I would include a trip with Red on the alleghany, and at least one or two days with Todd Young on Chautauqua. But thats is what I would do.
