In Three Rental Sites to Help You Kick Your Hotel Habit, we introduced major vacation-rental booking sites that offer an interesting alternative to the run-of-the-mill hotel stay. But there's more than one way to ditch the hotel and unearth a unique—and more affordable—place to lay your suitcase. Try swapping your home for an oceanfront condo on St. Thomas, sleeping in a fellow traveler's spare room for free, or working on an organic farm in exchange for fresh meals and a room with a gorgeous country view.
Here is your one-stop resource to alternative accommodations sites. We've divided the following into three categories: booking sites, hospitality networks (sites that connect travelers with free hosts), and home-exchange sites.
