I find it is usually cheaper to book on your own, but on one trip it was cheaper to use the Princess Hotel. That was for Copenhagen, but the cruise was moved to depart from London instead. Princess moved the hotel booki g at no additional charge (we'd already paid in full by mistake). We arrived 3 days ahead of the cruise. We were greeted at the airport by a gentleman holding a sign who took us to the hotel in a large comfy vehicle (don't know what it was). This was early morning and we were able to checkin to the hotel. Breakfast was included (delicious buffet or you could order off the menu - no charge). As others have said, luggage is picked up in the am by staff for the bus, we had breakfast and boarded the bus. We were the last people to board and they were looking for us. We were told to arrive between 1030 and 11 for the bus. We didn't want to have to stand around, so left about 10:50. I would be there earlier, rather than later. The room was lovely, the hotel was lovely, the breakfast was lovely; an all over first class experience - if the price works out or is comparable I'd do it again in a heartbeat.
