I also got an email last weekend saying there was one week left but the current promotion has always been up to 22nd October and I just checked their website and it says the same so I think it was a glitch on their promotional email system.
Tis a bit confusing just now. Going by the Disney UK travel site they have 3 dates for 3 different offers just now.
14 days for 7 passes on sale from 02 July until 31 December for stays in 2014.
$100 gift card on sale from 02 July until 22 October for stays in 2014
and Free dining on sale from 02 July until 05 November for stays in 2014.
Must admit i thought the meals and card were on till 5th November but glad i checked.
Just waiting for United seats to go on sale now for early September 2014 and i can get booking myself.
