We have flown the last three times we have gone and had no problems with Disney transportation. We never rent a car because I stress to much about getting lost. You will have to make arrangements to get from the airport to the hotel. 1 time we used Mears motor shuttle. 1 time a taxi and one time Tiffany town car.
A little about each. By the way, they all cost about the same for our family of 4. Taxi, a taxi is a taxi. It was there waiting and the person at the airport recommended it because-Mears motor shuttle, there was a line to buy a ticket and then you had to wait until they called out your hotel to get into a cramped van or a bus.
Last, Tiffany Town car. THE BEST they meet you at the airport waiting for you. They had a Lincoln town car to pick us up. Very professional and they were waiting and watching to see if there were any delays for our flight and if there were they would adjust their schedule. To come home we called a day before and told them what time we wanted to leave and they were out front of the hotel waiting on us.
Disney seems to push Mears, I am not sure why, I can guess, but I won't. Even when we left the hotel one of the attendants asked if they could get us a cab and we said no thank you, we were getting Tiffany transportation and they remarked they never heard of them. (hummm) There is car there picking people up at least once an hour and when we entered the lodge the attendant at the gate left the driver right through, no questions asked.
