Disney Answer: YES
Very few people realize that the Boardwalk are and Epcot are very close, just a few hundred yards separate the two. Everyone is familiar with the front entrance to Epcot, that is how most people arrive there, either by monorail, bus or car. But even if you are in the park all day, you most likely will not see Epcot’s second entrance, the International Gateway. The second Epcot entrance is located between United Kingdom and France in the World Showcase area of Epcot. As you exit the UK and head towards France, there is a pathway on the right hand side that heads downhill to a small shop right before you cross the bridge. If you head down that path, you will see the International Gateway right behind the little store.
From the International Gateway, you can access the Boardwalk Inn, Boardwalk Villas, Beach & Yacht Club Resorts as well as the Swan and Dolphin, and a bit further on is Disney’s Hollywood Studios theme park. If you are just headed to one of the resorts or the Boardwalk area, you can walk, they are just minutes away, but if you are going to Hollywood Studios (or maybe the Swan or Dolphin), hop on one of the boats and enjoy the ride.
The International Gateway operates just like the front entrance to Epcot, and is open the same hours. A bonus for entering Epcot through the International Gateway? The World Showcase does not open until 11 AM, so you get to walk through an empty, not yet open World Showcase, which is always a special opportunity.
