RxForDisney, as this is your first time at BCV and sounds like your first time staying at the epcot resorts area, please be aware of park closing hours (9pm for worldshowcase, i believe) if you intend on using the monorail as your mode of transportation to get outside of the epcot/epcot resorts area.
getting on the monorail from epcot to get to other parks and destinations probably isn't a very common to do (taking the wdw buses is faster). but for the novelty of it, we enjoy the using the monorail to get to mk every now and then.
it becomes a problem however, when you stay out past epcot operating hours, take the monorail back to epcot, and then realize that you cannot get back into epcot to get back to the epcot resort area.
this is a mistake you only make once, and for us we were lucky to have a cast member let us slip through, but we did see a couple turned away by another cm, i believe they needed to take a bus back to ttc to catch a bus to the epcot resorts area.
