I think this is yet another example or it depends on who you talk to. At my planning session, I asked my coordinator about letting the guests take the extra cake home in customized cake bags. Not only did she tell me that it was ok, but gave me a suggestion of something better than cake bags. (apparently it can get rather messy and difficult to put cake in all the bags. I asked about the rule of not taking anything leftover, and she said that the cake was the one exception. Since, couples pay so much for the cake they will allow them to take it back with them. BTW I am having my reception in Epcot.
