That does sound like a good idea. However if the OP were going to the Magic Kingdom when they have AM EMH and wants to be there for the opening, on that specific day it's not a good idea to get the Monorail from the TTC since it would not be running during AM EMH. Of course if it's the standard 9:00 AM park opening for both onsite and offsite guests, then it's something which could be done.
