They are both fantastic! If you want to be closer to EP, choose BCV (we like the woods view side). If you want a quieter resort, choose YC. Honestly, I love them both and don't think you can go wrong with either, so I would choose the one that's least expensive. BCV will have a full coffee pot and not the pod coffee makers if that makes any difference (we like the big coffee maker LOL!)
IMHO, I wouldn't book a 1-bedroom if it's just a couple. It's too much space for us and I never use the kitchen (just the coffee maker!). We like the studios with only 2 people. I actually prefer to have one bed and then a couch to sit on during the day. The sq. footage of both rooms is about the same (BCV studio 365 sq. ft., YC standard 380 sq. ft.), but with the sleeper sofa instead of a bed, the studio feels bigger to me
