If you cruise and a satisfied with a nice room, attended a couple of times a day, good food 3-5 times a day, relaxation on a balcony or pool deck, then YES, you'll be fine with RC's smaller ships.
If, on the other hand, your require a large variety of entertainment/play options, want to have multiple restaurant choices, and enjoy mobs of people everywhere, you'll probably NOT be happy on RC's smaller ships.
