Jan - I don't know the answer to your question about the luggage, but we stayed at the Bernini Bristol last year thru RSSC and we loved it. Great location, got wonderful restaurant recommendations every night from the Concierge, room was very nice, its an old hotel but they have updated the rooms nicely, they have a wonderful rooftop bar with great views of St. Peters.

My recollection was that the only excursion they did on disembarkation day was a city tour for those going to the airport with late flights. We transferred with them, but they took us right from the ship to the hotel, there weren't any other options.
