Hello Donna, and welcome to the wonderful world of the Disney Parks Moms Panel! I love exploring Disney Resort Hotels, and there are a few different ways to travel between them while you're visiting Walt Disney World Resort.
Disney's BoardWalk Inn and
Disney's Grand Floridian Resort & Spa are two of my absolute favorite Disney Resort Hotels. There are a few different ways to travel between them but since you're looking to get there at Lightning McQueen speed, I'd recommend
Minnie Van Service. Using the Lyft app, you can request that a Minnie Van driven by a Disney Cast Member come pick you up, and drop you off at your destination. Each vehicle sits up to six people, and even comes with two car seats for our littlest guests. There is a cost associated with this service, but if speed is your priority a Minnie Van is definitely the way to go.
If you're starting your journey at Disney's BoardWalk Inn, you can enter
Epcot through the International Gateway, which puts you right in World Showcase. From there, you can walk to the front of the park and use the
Walt Disney World Resort Monorail System or
Walt Disney World Bus Service to get to Disney's Grand Floridian Resort & Spa. This will take a bit more time than the Minnie Van Service, but it is complimentary to all Walt Disney World Resort guests.
Enjoy your vacation, Donna!
