I really don't see them running the express monorail to service the guests parked at TTC. The managers of the Contemporary, Polynesian and Grand Floridian would be slammed with massive amounts of complaints.
If you were going to run anything it would be the resort monorail as it services both resort and non resort guests. Based on what was written earlier I am going to go out and say that its highly unlikely that the express beam will stay up any longer than 1 hour after park closing.
Actually, the express monorail only runs for 1 hour after MK closes anyway so there isn't any real change there.
I agree. It only makes sense to run the resort monorail if you are only going to run one because it can serve both the resorts and the TTC.
