Many avid cruisers love sailing in September and early fall when ports are less crowded with tourists and cruise lines often offer slightly lower prices during shoulder season. As long as hurricane season storm activity doesn’t pick up, you can usually enjoy wonderful weather on a Caribbean cruise in the early fall.

If you’re planning to sail as a family, you’ll find a lot of value and family-friendly activities included in cruise fares on most any cruise line. Most cruise ships even feature kids’ clubs that offer fun, supervised spaces for kids to play at no extra charge while parents enjoy some alone time during their vacation.

Even if school and work commitments won’t allow your family to sail in the fall, you can score a deal by booking your family cruise vacation during the month of September. Right now, multiple cruise lines are offering limited-time Kids Sail Free deals for new bookings made in September.

While taxes, fees, and port expenses are not included in these Kids Sail Free and free third and fourth guest offers, they still provide significant cruise savings for families.
