Find a hostel at your destination by going to a listing website, such as Hostelworld. Read through the descriptions carefully and make a list of those locations in your price range. Then, take a look at the recent reviews. Hostels are often good options for travelers who enjoy a lively, young, group-friendly atmosphere.  Be aware that many hostels place multiple people in the same room, even from different parties. Make sure that you are comfortable with this before booking. Some hostels have communal kitchen or laundry spaces which can save you some serious money when traveling. Many websites, like Airbnb, now offer travelers the option of staying in someone's home. You can do everything from renting a large house to staying on a couch for a few days. Carefully consider what you prefer before booking, such as how much privacy you'd like. Read all available reviews and contact the owner with additional questions.  Many of these sites handle the payment process, so that no cash is exchanged on site. Trust your instincts when going this route and never stay in a place that you feel is unsafe. Head to a place where you know you have a free spot to stay. Make sure to give them your dates well in advance to make sure it's okay to come. If you are lucky, your friends or family might even offer to serve as free tour guides of the area. To help out and still save money, you might offer to buy groceries or cook during your stay. Stop by a local market and grab the makings of a picnic. Book a room that has a fridge or kitchenette that you can stock with groceries for your vacation. Eating out can be an experience, but so can chatting with locals as you decide what food to buy. This is a great way to try out an area's specialty foods. If you don't have the option to make full meals, grab a few snacks at a local store to carry with you.
