Tired of traveling by yourself?

Globetrooper.com

puts you in touch with like-minded travelers seeking global adventures and could help you avoid paying that dreaded single supplement.

What's hot: The site focuses on adventure travel, and you can chat about plans before booking. Focuses on regions rather than a country. I liked browsing the "Global Guide" for dream trips, such as an overland trip from London to Cape Town, South Africa, or cycling through Vietnam and Laos.

What's not: It was difficult to figure out how to book a trip. If you're looking for just a weekend getaway, this might not be the site for you.
