You'd be hard pressed to get it done in a week. You need a min of two days each in Panama City and Pensacola plus a day each in Destin and Mexico Beach. The other issue is the Oriskany trips cancel as often as they go. I've tried four times and only made it to the "O" once. I live in the area and go diving several times a year and I still haven't finished the trail. Still need the Vemar. If you had a week of awesome weather and were able to pick all of the dive sites for your trips, you might get it done, but your chances of that are about 1%. If you only have a week, I'd stick with Pensacola and Panama City. Skip the Miss Louise in Destin and the Vemar in Mexico Beach. You have a much better chance of getting good dives that way. In Pensacola, I'd recommend the Y-Knot or H2O below. In Panama City, go with Panama City Diving. Great dive op.
