Peter11435 is correct. They may shut down the monorail but you will never be stranded at a Disney park. We once "really took our time" leaving the Magic Kingdom one night and we hopped a bus to take us back to CBR but made stops at what felt like 6 other resorts before getting us to CBR. The driver was very friendly and joked with the passangers on the bus all the way.
Have fun!!!
