Hi Shannon, welcome back to planDisney!
Thanks for including so many important details in your question, Shannon. Your stay at a Disney Deluxe Resort at Walt Disney World Resort combined with your ticket with the Park Hopper Option qualifies you to attend
Extended Evening Theme Park Hours during your stay. On the night in question, you get to decide what attending looks like. If you're ready to head back to Disney's BoardWalk Inn after enjoying Happily Ever After at Magic Kingdom Park, you can take the monorail to the Transportation and Ticket Center, switch to the EPCOT Monorail, enter the main entrance of EPCOT, walk halfway around the park, exit at EPCOT's International Gateway entrance, and walk to your resort. My only request is that you stop for a picture in front of Spaceship Earth, which is absolutely stunning at night.
If you're interested in adding an extra thrill to your night, use your
My Disney Experience mobile app to join the 6:00 p.m.
virtual queue for
Guardians of the Galaxy: Cosmic Rewind. You should confirm your party in the app (three small lines at the bottom right of the app's homepage > Virtual Queues) by 5:58 p.m. and click "Refresh" > "Join Virtual Queue" right at 6:00 p.m. You can do this from Magic Kingdom Park while eating at Casey's Corner or waiting in line for Big Thunder Mountain Railroad.
If you're looking for the quickest route possible back to your bed, you can catch a bus from Magic Kingdom Park to Disney's BoardWalk Inn. If you end up getting a second wind you can always enter EPCOT's International Gateway entrance for a late-night ride on Remy's Ratatouille Adventure.
Hope to hear from you again soon, Shannon! You've got questions, planDisney's got answer.
Choose magic,
Jennifer
