For the lowest fares, book a Caribbean cruise in the fall — once kids have gone back to school.
"The one caveat is that you'll be traveling during hurricane season — so cruising in the Caribbean is best for those who are looking to save on your cruise vacation," McDaniel said.
Also, if you sail during hurricane season, be prepared to sail to ports that may not be on your original itinerary. According to US News & World Report, cruise lines can easily rearrange itineraries or can bypass a port based on weather conditions. Generally, there's no compensation for missed ports, shorter stays in ports, or a totally new itinerary.
Travel experts say to consider travel insurance. If you're sailing during peak hurricane season — September and early October — purchasing trip cancellation insurance can save you from forfeiting the entire cost of your vacation.
