I can give you my honest opinion about BCV, but it is not the popular one. I was let down, but mostly because of all the hype on the Dis about it. What I have found is that BCV is so beloved by people here, anything negative is shot down.
1. Location-It was good, but I didn't feel it was any better than Boardwalk and it was convenient for Epcot, but not rope drop at Epcot. They don't let you into International Gateway until they let people into the front entrance, so you have quite a walk in comparison and we basically missed rope drop. Also, while it is nice to be steps away from Epcot (and walking distance to DHS), Epcot is a huge park and honestly getting back to the room is not that convenient. The busses were horrible when we were there, but I have found this true at most of the resorts close to a theme park...if you want to go anywhere but to the close park it is just frustrating.
2. Pool-Yes it is huge. Yes, it has the best theme of any pool on site. But, there are also issues with it. It is very crowded, the slide entrance is outside of the pool area (so keep that in mind for your kids), but our biggest issue was that our kids were very small when we went. The kiddie pool and slide were at the steps to the slide and not at the main pool. We were in a knee deep pool and as adults couldn't do anything but sit on the edge and watch our kids. Our kids are older now and I wouldn't have a problem with them going on their own to the entrance of the slide, so its less of an issue now, but it is still crowded.
3. Rooms-OK, this is probably my biggest disappointment was the rooms. Yes, they needed updating and there was a lot of wear and tear, more than the other resorts I had been to. But, there location....The
DVC rooms were built as an addition, so they are not connected to the main building and actually run perpendicular to the main building. Of course were at the very far end of the building. It took forever to walk to the front of the resort, I stay at SSR most of the time if that tells you anything. But in fairness, this is true for a lot of DVC resorts, they were additions and not part of the main building like the hotels are.
With all of that being said, did I hate BCV, no. But I was disappointed because I never heard these things about it and it is just put on such a pedestal here on the DIS. I would stay there again, but with an understanding of what I was getting myself into and I would probably enjoy my second stay much more than my first.
