Well your trip is next spring and lots can change between now and then (hint, hint). Think of this as infrastructure maintenance and improvements before you arrive next spring....Taking the Monorail into MK and EP is one of the Poly's big perks and I don't want to lose that.
Reminder: You also have the Resort Motor Launch (boat) direct to the MK and 1 stop at the GF on the way back as an option.
