Well, the two bedroom will give you more space to spread out, so that would probably be my first choice, especially since you aren't guaranteed connecting rooms at YC/BC. Since there are only four adults, it probably won't matter so much that some of the sleeping space in the villas are sofabeds. With both options you will have two full bathrooms, although there is more bathroom space in the villa as well. If you were staying longer, the villa would be an even better option because of the kitchen and washer/dryer, but for such a short trip, that probably won't factor in. The only other issue is whether or not you feel Stormalong Bay is a dealbreaker. We're not big on public pools, so it wouldn't matter to us. But SAB is considered by many to be the best pool at a Disney resort, so it's another thing to consider. Also, the villa will have a regular balcony, as will the YC, but you run the risk of a small standing room only balcony at BC.
