Hi, I am 30 and just signed up and pretty much in the same boat! My friends and family are all doing things that i am not that interested in doing, i want a bit more adventure and to make the most of my holiday at the moment. I think you just have to pick a holiday that you like the look of and just go and enjoy it. I am sure from reading posts that even if you are younger people will still speak to you and include you, i would think as well that age does not really matter, enjoying your well earned break is more important!
