Just a note. There are no free shuttles from Marriott World Center/Palms complex to Disney. There are complementary on demand shuttles from the MVCI Palms Villas to the World Center Hotel itself. We just got back from there and had a great time. When you are looking at Taxi fees you have to take into consideration that "close" is a very relative term when you are talking about the size of the Disney parks and resorts complex.
