We are a couple in our 50s and this was our 17th cruise (3rd on Celebrity). We love cruising and have learned to always enjoy the great parts of cruising while not letting a couple not-so-great experiences ruin a long awaited outstanding experience.
We arrived a couple days early to San Francisco not ever having been there before. Anyone who has a chance to take a cruise out of this incredible city should do so. I understand not many cruises or cruise lines use San Francisco, but it is a great place to visit and sail from. The sailaway under the Golden Gate Bridge is spectacular. We stayed at the Chelsea Motor Inn, which turned out to be an excellent hotel, "moderately" priced, and near enough to Fisherman's Wharf. There was a Dreamforce convention in town with 150,000 attendees, so anyone who didn't book a hotel a year in advance like we did ended up either staying by the airport or paying extremely high prices. Infinity herself was docked for 4 days and used as a floating hotel for the convention.
The ship was in good shape other than some worn carpet and a little rust here and there. Hopefully stuff they will take care of at her drydock this month. Activities ranged from trivia competitions to some excellent educational lectures on marine biology and port lectures. There were especially good lectures and films on the Panama Canal. One of my few criticisms of Celebrity is their lack of a movie venue. They did show movies in the Celebrity Theater, but they were always on port days when we were off the ship. I understand that a rooftop terrace with a movie screen will be installed on deck 11 at the drydock, which should greatly increase entertainment options.
Cabin location was excellent and very quiet. It was convenient to walk downstairs to the Oceanview cafe and just a close elevator ride down to Blu. The balcony has a slight overhang but for the most part is exposed. We chose this portside cabin so that we would be in the shade in the afternoon while traveling south in the hot Mexican/Central American sun. It worked out well so the temperature was pretty much always cool. Coming north from Colombia, where we were in the afternoon sun, the cabin was a little harder to keep cool. I don't know how quiet this area will be once the rooftop terrace is built.
Other than the fabulous view of Lands End as we approached the harbor, there was nothing in Cabo San Lucas we wanted to do. We are not snorkeling or outdoor people and had we been, this might have been a place with lots to do. We spent most of our time downtown avoiding the numerous and aggressive street vendors.
