Affordable Winter Vacation Ideas Abroad

1. Atlantis, Paradise Island

Believe it or not, this sprawling Bahamas resort can be an affordable getaway, especially if you are willing to travel outside of the holiday break in December and winter recess in February. Mid-week rates start below $300 a night, which includes admission to the Aquaventure Water Park and the world's largest open-air marine habitat with more than 250 species of animals. And let's not forget the pristine private beach with crystal-clear Caribbean water. It's called Paradise Island for a reason.

2. Belize City, Belize

While Belize is a Central American country, it's often grouped in with the Caribbean nations due to its former ties as a British colony. It is also the only English-speaking Central American country, making it easier to visit for people who don't speak Spanish. Belize is rich in history, and the Mayan ruins are a must-see. Beautiful beaches, resort pools, lush landscapes, and easy-to-spot native animals make Belize a fantastic destination for families. The average temperature is around 83 degrees Fahrenheit during the winter months, which also don't see as much rainfall. Hotels start at just over $100 a night.
