Hi, Staci!
While the answer to your question is no, do not be disappointed. Disney's Beach Club resort is just a few minutes' walk to the "back door" entrance to Epcot, the International Gateway. That's even better than riding the monorail to get home!
Take a look at this
map of Disney's Beach Club Resort. The pathway that runs along the edge of Crescent Lake leads directly to Epcot's other entrance, right between the United Kingdom Pavilion and the France Pavilion. It's so convenient, I've booked our next stay for that same resort; you'll love it!
The monorail from Epcot runs from the park to the Transportation and Ticketing Center. From there, Guests can get off that monorail line and get on the Resort Monorail line, which will take them to Magic Kingdom, Disney' Grand Floridian Resort & Spa, Disney's Contemporary Resort and Disney's Polynesian Resort. Of course, you'll be able to get to Magic Kingdom via Resort Bus from Disney's Beach Club Resort, so you'll only want to use the monorail to get to MK if you're already in Epcot and feel like park hopping to MK.
Have a wonderful trip, Staci! Send more questions as you think of them; we love to help!
