In over 30 trips to WDW, in the beginning we drove, throw in 3 times by plane and then some more driving trips and now we have been using Amtrak for the pass 6 years, we have never used or rented a car at WDW. Part of the magic to us is using the transportation system there. Its a vacation, you're susposed to relax and smell the flowers. Can't be in a hurry, nothing is gonna change or leave or move. Everything can be seen and done at the World without going commando and the traffic of cars and people heading to the parking lots and then leaving same is funny as we either board our bus or monorail for a leisurely trip back to our resort. The red tail light parade leaving the park lots is a sight all in its own and unless you know where you are going at night with all the traffic looks like a chinese fire drill.
Even with our car in the resort lot, we never use it, like the idea, after driving 1200 miles to get to WDW, that I don't have to see that thing until its time to leave and drive the 1200 miles home. Really got to hate driving and don't really care to fly and for me and wife, the train is the most relaxing, pleasant way for us to go the 1200 miles now. We plan on using wegoshop.com this trip, but have walked to Goodings for supplies but thats a long walk and coming back worst with all the bags. Its each his own on how you do the World, this is just our way and my opinion.
