In the past 20 years, my husband and I have been fortunate enough to take 29 cruises, with 26 of them in the space of the past 11 years. We've been on a wide variety of cruise lines, from the most basic up to the deluxe Azamara and Oceania (one each). Crystal is the only luxury line we've taken, and so far we've done one on Symphony and now this one on Serenity.
Our ship overnighted in San Francisco. We boarded around noon, which was a breeze. A crew member escorted us from deck six to deck five, and five minutes later, we were free to wander the ship, with all our check-in details taken care of. We had intended to have lunch in the main dining room but we were waiting for a friend whose plane was a bit late, so we had a light snack in the Bistro, which happens to be on deck six, where we had a perfect view of people boarding. Alas, by the time she arrived, we had gotten bored waiting, gone up to the Trident to share a burger, and then we forced ourselves to enjoy our third course of lunch, at Tastes.
Cabins were ready earlier than expected and we made our cabin attendant, Casia, who was possibly the best cabin attendant we've had in all 29 cruises. Then we spent two hours wandering off the ship at its space at Pier 27, up Embarcadero to see the sea lions at Pier 39. It really didn't take long, but we were also people-watching and talking about past visits to San Francisco. It was sunny and balmy, a lovely bonus. The next day we had a glorious day for more wandering. The Ferry Market (the outdoor with the local people) is always fun to check out, and then two of us went up to the top of Lombard St. and walked down. The other one of us went to the Golden Gate Bridge and walked a small way across (we'd done the whole thing two years ago).
