Hi Jacalyn,
Traveling around the Walt Disney World Resort on
Disney's transportation just makes life easier. No need to worry about parking or getting lost on the miles of roads!
To get to the
Boardwalk from Future World in Epcot, you can head towards World Showcase and exit through the International Gateway. International Gateway is located after United Kingdom and before France. From here, you can board a Friendship boat or walk to the Boardwalk.
From Epcot to
Disney Springs, you will want to take a bus from the front of the park to Disney Springs. However, if you are at the Boardwalk, you can grab a bus to Disney Springs as well.
Your ECV is allowed on most
boats. You may have an issue on the smaller boats that travel between
resorts in the Magic Kingdom area. So take the monorail to travel between these resorts and Magic Kingdom.
Wishing you a magical vacation!
Beth
