The Swan transferred my bags over to the BC this year, and it was an easy process. There is a cut-off time, however. I can't remember the exact time of last pick up of transferring bags, but I think it's early afternoon. Be sure to check with Bell Services, so that you don't miss that last pick up.
You will have to contact Bell Services at Bay Lake Tower to retrieve or have your bags delivered to your room. They will not automatically deliver transferred bags to your room.
It can take a number of hours for the completion of the transfer.
