We are leaving for Disney in two weeks and I am wondering if we should add the dining plan. We were planning to do the Lunch with the Imagineer (not on the DDP), but have now changed our minds. Have I waited too late to get decent reservations anywhere? We have O'hanas, but nothing else is in stone. We would love to go to SCi-FI, Prime Time Cafe, Coral Reef, and other great restaurants. Do I have any chance of getting in?
