The marketplace has salads, sandwiches (breakfast and others), and gelatto. There are also refrigerated areas where they sell frozen pizza, lunchmeat, cheese, etc. They have bread, PBJ, boxes of doughnuts, chips, etc. This is also where you can refill your refillable mug.
The only food I've eaten there are a roastbeef and brie sandwich on baguette, pistacio gelatto, iced tea, lemonade and coffee. Also in the store are the gifts, clothes, and mugs to purchase. As info, I did enjoy my sandwich.
The service is slow if there are alot of people in line for sandwiches and salads but refilling a drink is convenient.
If I'm purchasing gifts, I walk over to the Yacht Club side because their gift shop is much quieter, has a few different items, and doesn't have the fresh made food (which is why it's quieter). I don't know about using snack points to eat there since I've never been on a dining plan.
As to the rooms, they are pretty standard. You can get a king, two queens, two full and I believe all have a daybed. The rooms are a little larger than some of the other moderate and value resorts but to me the room is a room and nothing spectacular unless you're accustomed to staying in value motels (I don't mean to be snooty here, I'm just trying to offer a comparison).
Room locations vary from water views, parking lot views, garden/walkway views or SAB view. I've never had a SAB view and was considering to request this for my upcoming trip but some of the SAB views look very blocked by rooftops that are over Beaches and Cream. If you want to see the layout, go to
http://www.disneyzone.net/bcresort.htm. It shows room numbers, where they have balconies, etc. We've had water views that were 1) near the back main entrance 2) over the volleyball court 3) near EPCOT and the stairs that exit to the side walkway (I like this because we frequent EPCOT alot and could just walk to the stairwell and up two flights to our room.
My only request for my trip next week is for a full balcony. I suppose the only disappointment I'd have is with a room that was over the main entrance facing the parking lot. Other than that, I'm going to wing-it. I think it would be nice to have a standard view near the walkway close to EPCOT.
The rooms on the top floor seem to have dormers giving the room an attic feel but I'm not sure if all rooms on the top floor are like this. It almost doesn't matter where you are as far as close to EPCOT, the lobby, elevator, etc. No matter what there's going to be a long walk somewhere if you're going to the giftshop, pool, Cape May, EPCOT, Boardwalk.
This is our favorite resort because of the location. I hope you have a great time and get to enjoy SAB!
