Carnival Triumph attracts a fun-loving, diverse group of passengers who tend to hail mostly from the region where the ship homeports. (For 2015 through 2017, Triumph will homeport from Galveston and New Orleans.) Expect to see families, girlfriend groups, couples, coworkers, church groups and large posses of friends, many wearing matching T-shirts.

You'll also see lots of kids; during the summer months, there can be as many as 1,200 passengers younger than 18. And finally, Triumph attracts a lot of first time cruisers. On most voyages, more than half -- sometimes as many as 75 percent -- of passengers are on their first sailings.
