Denise aka Stunned - beaches and creame probably can if you can go to different tables - the tables will sit 4, the booths will sit 6, the fountain sets will take 14 (?) if they are all vacant (unlikely) when you arrive - this is a very small place - so even if you have sit apart - it won't be very far.
WDWDad - for my niece's birthday I got a birthday cake (Winnie the Pooh) from the Publix, they had other Disney characters available too. They also told me (last year) that they could made what cake I needed in 24 hours notice.
DayDreamin - I have not celebrated any days or parties at VB. But when we were there in September the CM were outstanding - call them tell them what you want - or see what ideas they have (they are very creative people). They really go out of their way to make your trip as pleasant as possible.
