Nicaragua ended up on our Top Budget Destinations of 2015 for a reason. This hot deal is just one example of the destination's affordability -- and at a time snow is frosting over most of North America, too.

Aqua Wellness Resort, tucked into a forest along Nicaragua’s Emerald Coast, is offering fourth nights in their treetop villas or suites for just $15. This means that you can end up paying average rates of $142 per night for a treehouse featuring a queen bed and wraparound deck. (Regular rates, if you want to do the math yourself, start at $185.) We dug around and found these rates available for the weeks of January 20 and 27, February 3 and 10, and others throughout this winter and spring.

The deal must be booked by February 15 and is valid for bookings of four nights through July 15. Again, bunk in either a treetop suite or a villa, affording stellar views of the resort’s private beach. To book, visit this area of the resort’s website and plug in your travel dates. This promo is automatically applied, so you don’t need a booking code.

Two dining options are onsite: The beachfront, all-day Oceanside Restaurant serves low-sugar, tropical fruit juices (like dragonfruit and passionfruit), locally grown produce from nearby Rivas, and hormone-free meats; a bar/lounge touts smoothies, lattes, and more juices alongside beers and cocktails. Elsewhere at the resort, guests can dive into yoga and kayaking, surfing and meditation, or stand-up paddle and cooking. Of course, there's always a spa treatment for extra pampering, or the staff can also coordinate day trips to the nearby colonial town of Granada, surfing hot spot San Juan del Sur, or UNESCO Biosphere Reserve Ometepe Island.
