The notion of sleeping in a room of bunk beds in close proximity to seven (give or take) snoring strangers on your vacation might not seem like the most appealing option for lodging. However, Hostelworld isn't just that classic idea of hostel-ing. Hostels are known for being budget-friendly, and a great way to meet like-minded travelers, especially for solo explorers. They're becoming even cooler, encouraging travelers to be social in some amazing common spaces. Many offer private rooms and even private bathrooms, amping up the hostel game for those who aren't into re-living their college days. Still not your thing? The site also has hotels and bed & breakfast options.
