Also because of the small number of passengers, the itinerary can be flexible. You can stay for the evening for a local festival, stop to watch a whale, or launch the zodiacs in minutes if there is something special to see. On some expedition type cruises, accommodations can be spare, with a shower that gets the entire bathroom wet and a rack on the wall for clothes instead of a closet. But usually you will be able to hike through rainforests, swim, or sightsee all day, then come back to fine room, a hot shower, and an excellent dinner with wine. On some ships you may have a vcr, cd, radio or phone in your cabin.
Some vessels have a masseuse, some have a sauna and some have elaborate spa facilities.
You get friendly service and personal attention on almost any ship. If you want to really be decadently spoiled, you can try the white-glove treatment of the luxury ships. Some of them have private verandahs, marble baths, terry robes, personalized stationery, and champagne and caviar at any time of day or night. And some have full spas. On the luxury ships you dress for dinner every night and one or two nights a week are formal.
