I want to comment on 2 areas that were tricky for us: Activities and Entertainment. My husband and I cruised with our 2 sons who are in their 20s. The food, the glaciers (too fleeting) and the piano bar saved the cruise for us. Enjoyable cruise overall but we had to find our fun. Mostly, for all 4 of us, that fun happened between 10 and midnight in Michael's Club with the talented pianist/vocalist.
Many of the activities involve alcohol (which we drink but we can only chug down so many drinks). ire a fee or are mainly to plug a product, e.g., demos of the language learning computer software, Rosetta Stone. Playing Monopoly with fellow passengers was more fun that participating in staff led trivia and other games. The staff was disinterested and wanted to get the activities over with. A bright spot was the naturalist---he knows his stuff and he knows how to deliver it. Crowds were large to listen to the naturalist talk about whales, glaciers, the moon, etc. His lectures provided passengers a worthwhile way to spend time while staying half sober. Fitness center was fine, but often crowded and we had to wait for cardio machines. The casino can't be open as much as perhaps when sailing to other destinations because of strict laws in Chilean waters. So, with the activities rather drab we looked to the entertainment....
The staff harped on getting guests to sign up to rehearse and perform in a final show. There were few takers and we didn't attend this show. The band in the main lounge and the party band needed practice. An A Capella quartet was good but they played very short sets. A guitarist, Cisneros, was quite pleasant to listen to in the Atrium or aft cafe deck. But our favorite pastime was to head to the piano bar to hear the ship's pianist/vocalist, Tom Listabarger. Tom is outstanding; he can play about any tune you request and really accommodates his audience. I'm not sure what we would have done were it not for the piano bar option each evening. We'd usually went to the Celebrity Theater shows and they were okay, but we wanted more than 45 minutes of entertainment. We found it odd that Tom isn't publicized beyond the routine listing in the daily newsletter. The cruise director would tout the "Starring You" (passengers performances) and the disco but never mentioned the piano bar. Don't believe Tom ever played in the Atrium either---you had to catch him late at night when most passengers were asleep.
Expect a relaxing cruise, good cuisine, interesting ports of call and the best pianist/vocalist at sea. If you want anything else, pick a different cruise.
