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. Some cruise lines also charge for room service. So, read all the terms to know hidden and additional charges.

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. Don’t pick a cabin next to the staircase, elevator, dining room, lounge, or spa to avoid hearing people’s voices day and night. Pick one that doesn’t have a non-cabin above it, or get ready to hear tromping all night. Balconies are overrated, and cruise lines charge a bomb for that extra real estate. You get more space, but they are blocked by girders, open to decks above, or sometimes placed directly above lifeboats. Check the deck plan before swiping your card.

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.
