If I had a choice in where to stay, how long and where to go I would do a full run through of disney. I believe that I would stay in muiltiple hotels, 1 per week. These hotels would be the Animal Kingdom Lodge, the Polynesian Resort and Spa, the Boardwalk, and Fort wilderness. I would go during the early spring when the weather is just right. I would not try to cram all of the parks into muiltiple trips. I myself like to watch the details and let the day takes it time. Only using fastpasses for the big rides. Thats what I would do in my dream trip.
