Hi,
Good luck! I was in exactly the same situation as you this time last year, did the summer season with Britannia, has an absolute ball, loved every minute of it and earn't loads of dosh!
After the summer I joined Virgin, which is where I still am now, with a better tan but a much worse bank balance!
Enjoy your time at Britannia, they are an ace company to work for!
Where will you be based?
