You could request Epcot view, but many of those aren't really that great, and the service road is down there. You can really only see the Epcot fireworks if you're up high, top floor mostly.
They don't have any 'official' Epcot view, it's just they'd try to put you on the Epcot side of the building.
You could request near elevators if you'll be coming and going a lot.
I personally prefer one of the pool views. It gives more of a resort feel when you look out the patio window.
Here's a satellite image of Epcot. The BCV is that light color 'Y" shaped building about the middle of the image and off to the far left side. You can see that one leg of the 'Y' is toward the parking lot. The interior of the 'Y', or the 'U' shaped part of it, all face the pool. You can pretty much judge the remaining views as either being toward Epcot, or toward grass/trees, or toward the main building areas of BC.
Hope this helps
Just for fun, other things in the image:
Lower Left corner is BWV and BWI (just barely visible). Mostly you can see the parking areas.
Top Center is the guest parking area for Epcot
Right Center is the CM parking area for Epcot
Bottom Right is Carribbean Beach Resort.
The Epcot area should be pretty straight forward, with Spaceship Earth at one end, and World Showcase at the other.
Even though BCV is very close to Epcot, you have to walk to the main walkway and then to the IG to get in. It's still a very short walk, but not like walking across the street where Epcot is actually situated.
