Cruises are one of the most relaxing vacations replete with fun. And there is a range of things that cruise lines would rather not tell you? Since most cruise lines are sales-based, profit is one of their important motives. There are quite a few tricks up their sleeve devised to encourage you to spend more. To save you from these traps, here are four cruise secrets you should know before you book your next cruise.

All-inclusive packages are not all-inclusive

Most all-inclusive packages only include room stay and meals cost. Beverages, tips, shore excursions, internet, activities, and dining outside the dining area are chargeable.

Cruises are not crime-free

Big cruise lines keep a tight watch on crime, but sometimes bad things can happen. Cruise lines are not required to report thefts of less than $10,000, so not everyone knows much about the rate of petty crimes. However, you should always be careful of your surroundings. For safety, do not carry valuables items on vacation. Some cruise liners have a prison or a “brig” to lock up unruly passengers, later handed over to port authorities.

Your cabin will be noisy

Cruise cabins are notoriously not private.

The ship will not wait for you

If you have disembarked on an island or port and not returned on time, the cruise can leave without you. The captain may wait for a while if they are missing a busload of tourists, but if one or two people are missing, they may have to find another way to reach their destination.
