I went 6 June last year. There are alot of American's there for 'Grad Week'. They're all basically eighteen so there are alot of younger people there. But they're good fun!! There were 20 of us aged 21-27 and we liked it so much we're going back. Most the people there from the UK are about 24 plus.
yea, most people we met were 20 ish (I was 19 at the time)...You meet alot of ppl from all age groups thoughbut i'd say if there was an average age it would be 21/22
