4. Carnival
With a history of four fires and two other major mechanical issues, this family-friendly cruise company doesn’t have the best track record in the last 8 years. The major incident occurred in 2013 when 4,000 passengers were stranded in the middle of the Gulf of Mexico for four days with no hot water and more non-functioning toilets than functioning ones. Along with this awful history, these cruises are overcrowded and often full of drunken adults and rowdy kids. Mediocre food, small sun decks and way too many activities to choose from coupled with small cabins that you can barely turn around in make this cruise company one to avoid in 2015. If that isn’t enough to make you avoid Carnival, consider that two people have gone overboard this year.
