I know I won't get flamed on THIS board for my comments. I've never seen what benefits there are for staying Disney.
Disney Transportation... I've always had a rental. You can get them quite cheap. After having your own car, I wouldn't put up with waiting in lines for full buses that make multiple stops, or waiting at the airport for an hour just to hop a ride to your hotel. I prefer to go where I want when I want. And, that includes eating where I want at prices I prefer.
Extra Magic Hours... I avoid any park that has extra magic hours. I originally had booked Wilderness Lodge for my next trip, and even then my itinerary went against EMH. Not a benefit to me.
Room charging... a credit card is a credit card whether you pay for the item at time of purchase or in one lump sum at the end of your trip. Again, I personally don't see this as a benefit.
Package delivery... well I only tend to go in the stores when I go to Downtown Disney. Then it's a shopping day, and we have a car right there so what's the big deal in carrying your own bags? I'm a tad paranoid so I wouldn't use that system anyways.
So, for a THIRD of the price of a TINY bedroom that sleeps 4 at Wilderness Lodge, I can book a 2-bedroom condo with full kitchen, living room, dining room, huge balcony, washer-Dryer, etc. There are activities all day long for the kids. I have a car to come and go as I please. Yes, it's not officially on property but it is only accessible by Disney roadways. The only negative to me is not having a restaurant onsite, but neither do the all-stars.
I don't see the "perks" of staying at Disney to be worth shelling out 3 times as much money. I'll spend that dining/shopping instead
To the original OP: There are buses at BC, but on a limited schedule. I would really look into renting a car for your stay. If you look at mousesavers.com you can find all kinds of coupons and discount codes. You can often get a rental for under $200.
I'm not a first-timer but I think BC is a great choice, and maybe you'll be pleasantly surprised.
Here's an older thread with pics, that has some info on the buses too:
