We have gone to MK many many times and only parked there once. We did it so we could say that we have parked at all the Parks. The parking lot is confusing and you are further away. Most of the time at Epcot we walk from the car into the park. You sure can't do that at MK.
Mousekeeping was great but didn't take their tips for 3 days so I ran them down to Customs House! Ask away! The place was GREAT!!!
