I''ve got a 1-night pre-cruise stay at the San Juan Marriott thru Princess with transfers from airport/hotel and hotel/port. Our ship doesn't leave port until 11 pm on Saturday night. We would like to tour around San Juan during the day on Saturday before embarkation. When does embarkation begin for an 11 pm departure? What will we do with our luggage after we check out of our room until we are ready to go to port? Should we eat before we embark or will food be available on board at that hour? When will luggage arrive in our stateroom with this late of departure?
