We own a timeshare at BC and have been twice. We were just there last month. I've never stayed DVC before, but have stayed on property at Shades of Green once before.
I LOVE BC. PP has already mentioned a lot of the positives there. I will comment on the shuttle service. It is not as readily available as Disney shuttles. There are not as many return times early in the day as we needed when we were there the first time. I had real little kids, and they needed to come home for a rest. We found it easier for us to just drive ourselves. But, if you are the type who stays in the park for most of the day, they will be just fine for you.
The amenities at BC are unbeatable. When we were there last month, there was a daily activity for the children - a bounce house was blown up twice per week for the kids to play in for example. There are 4 separate pool areas, a play ground, putt putt, arcade in addition to the kids' activities.
The condos are a great size. The 2 BR is about 1200 sq ft I think and we have stayed in a 3 BR as well which was about 1500 sq ft. Love having all the space to spread out. It's always very clean and comfortable. We enjoyed grilling out by the pool in the evenings.
There is really easy access to restaurants and stores. You are right near the interstate so it's super easy to get places.
Anyway, you are more than welcome to ask me any questions as well.

Never argue with an idiot. He'll bring you down to his level, then beat you with experience.
