Cali, I don't know the number of queen rooms with daybeds, vs those without, but most of the rooms we've stayed in did have a daybed. Maybe Joe Cool's site here on the resorts board has more info. Our room was standard view, and looked out over the YC entrance and gardens. Remember, we were upgraded from a plain old standard room, so we were thrilled just to be in concierge! If you spend alot of time on the balcony, or looking outside, then go for the waterview of the lake and the BWI in the background.
For what we paid, concierge was definitely worth it! If you can get any type of a discount and there are more than 2 in your party, then it is probably worth it. We had breakfast from the lounge every morning, and brought bottled water to the park with us each day. Then we would get sodas and snacks to bring down to SAB in the afternoon. There were also appetizers around dinner time, and desserts and liquors in the evening. If you take advantage of all the offerings, then it can save you some money.
Since this was a surprize upgrade for us, we already had all of our PS made, and so we didn't take advantage of that service. All I know is that we are now officially spoiled, and it is going to be hard to just have a regular room!
