We just got back from the BCVs, and the Marketplace really was nice. Now, I don't really have anything to compare it to, since this was our first trip "home," but...
The refillable mug station was very convenient and totally self serve
The food looked good, and the dessert case looked great!
There were lots of grocery items - refigerated, frozen, and pantry. I forgot oil at the big grocery story we went to before checking in (was baking son's birthday cake), and they even had that. Oh, lots of Disney food too - cookies, candies, etc.
The selection of "gifts" seemed to be pretty good, and there were lots and lots of pins. Oh, and
DVC merchandise as well - shirts, decals, mugs, etc.
Beautiful place. And all the CMs we met were very nice.
