Howdy, Chris!
When staying at an Orlando area hotel, using Uber, Lyft, or a taxi is going to be the best option for getting to Disney's Grand Floridian Resort and Spa. If your hotel offers complimentary transportation to Walt Disney World, have them drop you off at the Magic Kingdom and then take a ferry or the Monorail to Disney's Grand Floridian Resort and Spa for your Advanced Dining Reservation for breakfast.
From the bus stop at
Disney's Grand Floridian Resort and Spa, hop on the first Disney's Hollywood Studios bus and head to the fun! Once you've finished your day at this theme park, you can either walk or ride the Friendship Boat to Epcot. The walk and boat ride are about 20 minutes and you will enter at the International Gateway at Epcot.
Once your magical day has come to an end...insert sad face...you can arrange for a taxi, Uber, or Lyft to take you back to your hotel.
Also, a rental car for the day may be an option for you depending on the number of people in your party. You can park at the Ticket and Transportation Center for the day and use
Disney's complimentary transportation all day to get you to your breakfast reservation, the theme parks, and back to your car.
Have the most magical trip EVER! Stop by and visit with us again if you have more questions!
