14. Costa Rica
Cost Rica, one of the best winter vacation destinations out there, offers stunning beach resorts and adventure sports like mountain biking or hiking through the Arenal volcano area. The beaches get crowded close to Christmas. If you can squeeze in an early December trip, prices will be far less.
15. Rio de Janeiro, Brazil
December is a fantastic month for weather in Brazil, although you can expect occasional tropical rain showers. Rio is a party city with tons of culture, beaches and a little something for everyone. Be sure to visit the stadium where the World Cup was played and see the sites being prepared for the 2016 Summer Olympics.
