If you are looking for the rope drop experience (the show), you'll need to drive or take a cab to the front of the park - since there is no transportation to the front of the park from BWV (I suppose you could take a really early bus to the MK then the early monorail back to Epcot if you don't have a car and are looking to avoid paying for a cab - that's a lot of time invested for the rope drop show though).
The distance to Soarin' is larger than what you'd get if you were actually at the front gate rope drop, so you have a slight disadvantage over those booking to Soarin and Test Track. But since they moved up from the IG into Great Britain, it isn't much of a disadvantage.
