One of the great advantages of BC (or any of the Epcot resorts) is that the IG entrance to Epcot is within walking distance of the resorts and is, almost always, a less congested and quicker way to enter the park. Entering from IG may cost you a couple minutes getting to some of the attractions in the morning, but it is no more than 5 minutes, at most. In order to save this de minimis amount of time, you would forgo one of the key benefits of staying at an Epcot resort and incur the expense of taking a cab from BC to the front of Epcot?

To each his own, I guess.
