People are always asking me, "Which cruise line should I choose?" Here are some quick tips to use to sort the answer out. The various vacation cruise lines have their own characteristics.
Decide what type of cruise you are interested in, traditional (assigned seating and time at meals) vs. freestyle (eat where or whenever you want), or family oriented vs. adult oriented. Then look at the cruise line that specializes in your preference. Of course Disney is family oriented, but so are some of the other cruise lines. Norwegian, Windstar, some of the Princess and the Disney cruise lines all offer "freestyle" cruises. Carnival, Royal Caribbean, Celebrity and Holland America tend to offer the more traditional cruises. Windstar is more adult oriented.
Disney Magic, Disney Wonder, Norwegian wind and Pride of Aloha do not have gambling casinos.
Decide what age group you want to be with on the cruise . There are some trends among the different cruise lines. Royal Caribbean's most common ages range fro 30 to 50. Windstar 35 to 55. People on the Princess lines tend to be over 50 years old, and Holland American range from 40 to 60. Of course on Disney the age is younger. Crystal cruise line passengers are generally in their 60's. Celebrity passenger range from 30 to 55 and Carnival tend to be fairly even across the board, the most 35 to 65.
Decide where you want to go and check which cruise lines feature those places. Of course you can always just do a short "no destination" cruise, where the boat is most of the fun. These are popular for fun, short, or spur of the moment cruises.
