We'll be checking in at BWV tomorrow!! We own at SSR, but have stayed at BWV more than any other resort. Like everyone else said, the location is perfect. We love the decor of the rooms, the walk to EPCOT and pleasant boat ride to DHS. We especially love the evening entertainment. We have three dds, 6,4 and 1. They love watching the events at night, and taking a surrey bike ride around the lake. It has great TS dining options especially when you add in S/D, BC/YC and World Showcase.
The only downside in our opinion is having to walk out to the boardwalk to grab a quick bite. The bakery is great for breakfast, but doesn't have many choices for lunch or dinner. Plus if it is raining, you have to get wet to get there, and there is nowhere to sit after you have your food except for walking back to your room in the rain. It's not a deal breaker for us, but annoying.
We love BWV, but are still glad we bought SSR. We wanted the extra years since we're young, and like trying all the resorts, so home resort advantage wasn't the most important factor for us when picking a resort.
Good luck.
