Think you got mixed up with the number of sleeps and the dates. Xotf is 17th dec 'we' decided the best bet was the sat directly before Christmas as the vintage year of 2007 being the 23rd was cutting it that little bit too fine!!
Errr if you want to go Amex has posted all the relevant info
Softlad... You on for 1 night or 2? I'd get ringing around direct to b&bs as they can be funny about just 1 night stays...dont bother with the 3rd party thing youll get more luck avoiding that route!
