Okay, I went ahead and purchased the Tour Guide Mike AVP, and I'm getting ready to re-work my park visiting schedule based on his advice. (My trip is in June, and I've already began planning my detailed itinerary! I love the planning almost as much as I love going on the trip!) This will be my 7th trip, so I'm no rookie, but I'm very nervous about re-working my whole plan. Has anyone else used this service and have any comments- good or bad?
