The big problem with that is that there is no CS option available at that time. If I remember correctly, Beach Club Marketplace closes at 9:30, and Hurricane Hanna's will have already closed as well. We have been through this several times now, and it is one of the reasons we aren't rushing to stay at BCV again. Yacht Club has nothing. And of course, Epcot will have already closed at that time as well.
Boardwalk Bakery should be open at that time, but Boardwalk Joe's will have closed, and then you are only left with TS options. ESPN Club does not do take-out (have tried several times). Boardwalk Pizzeria might be an option, not sure when the close? They sell slices and whole pies. Not sure about Swolphin hotels - their cafeteria style might be open (Picabu)?
The lack of quick food options at Beach Club/Yacht Club and Boardwalk during the day is a major downfall, but during night hours, there really isn't anything available.
Not sure about Club Level, as we have stayed at Yacht Club and Contemporary, and I'm pretty sure they were both closed at that time of night.
