I think this "you'll defo meet up with people" stuff is a bit questionable.
I stayed by myself and met up with people I knew that were down from London - good aquaintences, you could say - for about half of the nights.
I met up with some cool people in the clubs I went to by myself, but I certainly didn't meet anyone to "tag along with". And I'm an extrovert!
In my case, I didn't mind - it let me go and do whatever I wanted during the day, then hook up with people at night - but if you're the type that needs people around you, you might want to wait until you know other people that are going, or meet up with people from this board.
