Several years ago a friend and I arrived a day earlier than the rest of our party so that we could spend a night at the Grand Floridian.
A week there would bankrupt us, but fora very magical night it was wonderful. We did the whole nine yards, with a wonderful dinner out and breakfast delivered by room service.
While others might recommend The Polynesian or Contemporary, I think for one magical night to start your vacation the Grand Floridian can not be beat.
