The cruise line offers a lot of extras and many passengers seems to have the same regrets for what they bought.

The former crew member admitted to planting small cameras in cabins to catch record passengers, including children, nude.

A Royal Caribbean crew member, Bryan James, a guitarist for the cruise line, shared how birds are kept away from cruise ships when they're in port. It's actually a fairly ingenious method that you may not have even noticed when you're on board.

Some cruise lines, like Norwegian and MSC Cruises, sell cruises that are more inclusive than the fully a la carte lines, including Royal Caribbean and Carnival Cruise Line. Newer cruisers don't want to miss out and that can lead to some purchasing mistakes.
