I did the same thing. We had late seating and chose to eat at BBB. We left our bags in our cabin, ate from 7:15-7:45, went back to the cabin to "freshen up" and retrieve our bags, and walked off the ship at 7:55 (and didn't have to stop to search for our luggage). I never was comfortable with leaving my bags outside the night before-that's just me and my anal/obsessive/compulsive/neurotic self.
