Hi, i'm a newbie on this site, but am well travelled as a solo traveller. The nervousness is totally understandable if you have never done it before, but please dont let that stop you doing it, those nerves disappear withing the first 2 mins when you meet your fellow solo travellers. you are all in the same boat and all meeting new people, so always remember, you arent the only one who feels the nerves.....just smile and say hello!
