Just another item to throw into the mix. 10 Sq. feet is not much. I think the rooms are probably about 10 feet wide +/- a foot or two. Well that means the room is only about 12 inches longer.
Here are few other square footages you may like to add to the comparison
(Standard Rooms)
All Star Resorts -- 260 sq feet
Carribean Beach - 314 sq feet
Port Orleans - 314 sq feet
Coronado Springs - 314 sq feet
Wilderness Lodge Resort - 340 sq feet
Animal Kingdom Lodge - 344 sq feet
Beach/Yatch Club - 380 sq feet
Polyenisian - 409 sq feet
Contemporary - 422 sq feet
So it looks like no matter which one. The
DVC studios rank up there with Disney's deluxe hotels in size. (and you don't pay for a microwave or a refrigerator to boot)
