Don't expect the weather to always be good.
Don't expect the feds to be as understanding of minor mistakes at the CAA.
Don't order anything in large.
The beer is sh#%t.
The locals are usually very hospitable ( unless you give an honest opinion on the beer quality)
Enjoy it will be good fun but don't look at the price until you get back, in the cold light of day flying in the USA is not as cheap as you think.
Leave the pole dancing to the girls, if you have had enough beer to think you can do it you have had too much to try !
