We stayed at YC last November. We picked it because we preferred the lobby décor and were worried we wouldn't get a full balcony at BC. We had younger children with us and didn't feel out of place at YC.
That being said, we won't be returning to YC. I'm sure our experiences are the exception and not the rule, but we had a number of negative experiences at YC. My dad even popped in there on our recent trip (Sept 2013) ...maybe it's just crazy coincidence or dumb luck, but he got a YC CM who gave him bad info. On the flipside, the CMs at BC were awesome every single time we popped over there. There definitely was more chaos in the lobby- possibly because of Cape May breakfast, but if I had the ability to go back and redo the trip, I would definitely choose BC over YC.
