30 Insanely Affordable Warm-Weather Winter Destinations

Sometimes the key to affording your dream vacation is knowing when to go, and winter can often mean great savings, even for destinations that aren't particularly cold this time of year. Using information gathered from Google Flights and Google Hotels, we put together a list of both domestic and international destinations that are both warm and affordable.

These 30 destinations all clock in at under $350 round-trip for domestic and less than $500 round-trip for international travel, although it should be noted that these estimates are for flights to and from New York City airports and therefore the price can vary from other areas. For hotels, we set the bar at less than $130 per night at hotels in America and less than $200 per night at hotels outside the country.

Keep in mind that flight and hotel rates can easily change due to a number of factors, so it's important that you do your homework and make sure you don't make any common booking mistakes that could cost you, like booking at the wrong time of day or on one of the worst days for holiday travel. Choose one of these destinations and be savvy about hotel reservations and flight deals, and both you and your wallet will be happy about your winter vacation.
