Hi Josie and welcome to the Disney Parks Moms Panel!
Walt Disney World Transportation makes it so easy to leave the real world behind on vacation. It's so nice to not have to think about who is driving or where you've parked the car. With all of the options at Walt Disney World, everyone has their preferred mode of transportation. My children love the
Monorail but I'm a fan of the
Friendship water launches that run between Epcot and Disney's Hollywood Studios. I am sorry to tell you as long as the Monorail is operational, there is no
Bus Service to Epcot from
Disney's Grand Floridian Resort & Spa.
If you are not a fan of the Monorail, you might want to look into
Minnie Van Service. For $25.00 the Minnie Vans can take you from your Disney Resort to almost any location in Walt Disney World. The service operates through the Lyft app on your smartphone. I have used Minnie Vans several times now and have found the service to be delightful. Minnie Van drivers are all Walt Disney World Cast Members and they are very concerned about your safety and comfort. The Minnie Vans even have charger cords for your smartphones if you've run low on battery power at the parks!
Please let us know if we can help you with any other questions!
Wishing you a magical vacation,
Amy H.
