i only travel alone these days... it's definitely a LOT of fun - depending on your personality. i'm a total extrovert and i tend to meet people everywhere i go... so the last vacation i took to england and greece i had a total blast traveling alone.
the main things to remember are:
1) if you're going somewhere that you can't speak and read the native language, it's going to be a challenge
2) traveling alone means you can do what you want, when you want to
3) traveling alone means you can get laid as often as you please
go for it!
