I chose for the itinerary and no-charge specialty restaurants. I travel solo and like the choice of several restaurants where I can eat alone or join others. The Penthouse on Marina is very roomy, and you can order dinner in from any of the specialty restaurant menus. I like that buffet food is served to passenger's plate rather than self-serve which minimizes cross-contamination. On my cruise there were two main lecturers, one who concentrated on WWII and the other, more general on port stops and his travel experiences. entertainment is not lavish: singers and dancers and soloists (singers or musicians),who were quite good, and the occasional comedian. I have two complaints about Oceania: their shore excursions are greatly overpriced, and they are not totally inclusive: alcoholic drinks are extra +18%, and gratuities are extra. There are packages for drinks and excursions and usually a shipboard credit to help pay for extras. I didn't use the pool, but there seemed to be no problem getting a deck chair. Because of my itinerary Transatlantic and the time of year, there were no children on board. I don't think Oceania caters to children. I plan two future Oceania cruises which is the true test of satisfaction.
