If you ever visited the MK from off site, the trip from the TTC to the MK kinda builds up the idea that the ultimate Disney vacation starts at one of the monorail resorts (and although I've never stayed there, I still believe it)
Plus, as much as people make of seeing EPCOT fireworks from BWV, BLT MK views could see Wishes and the lights on the water parade every night.
The monorail would make it very easy to visit the MK (Which we frequent the most) and not too bad to EPCOT, Poly and GF restaurants.
Plus, it is just not a complete vacation without Chef Mickey's.
