Yeah in some respects I prefer travelling solo, I like being able to do what I want, when I want, without compromise. I'm comfortable in my own company so it really doesn't bother me. I've backpacked a couple of times in my youth on my own.
In Feb this year I did Kuala Lumpur, Langkawi, Penang, Ko Lipe, Singapore and Doha on my own. Was supposed to be with the gf but we split up before departure, so I thought fuck it lets crack on and had an amazing couple of weeks. Can appreciate why that wouldn't appeal to some people but personally I find solo travel can be almost liberating and strangely addictive.
Basically I'm a selfish twat! :)
