It depends on what resort and also what you are brining in. If you are staying at a DVC resort which have full kitchens, then bring what you want and what ever you want.
There are some posters who bring food with them to save money on the trip which is fine, with in a limit. DW and I bring breakfast bars and such for snacks at night while we are waiting for a bus at the parks,but nothing more. There are other people who bring coolers and fill them with ice every day to keep cold cuts and such but that's a little too far for me.
IMHO rooms are for sleeping not eating. The more people eat in the rooms the more crumbs get arround and then we have bugs in our rooms.
