We are off in 35 days

and we're also booked for the same time in October/November 2014. There are a bunch of reasons why we choose this time of year to go and one of them is that the 11 month window for booking flights coincides with the flight sales in December! Our dates this year are 29th - 12th, we booked the Disney portion of the trip in May or June 2012 to get the free dining, 30% off and free $200 gift card and then booked our flights in December in the BA sale. Interestingly, we paid £2500 fly drive with premium economy flights and inclusive car hire with
Avis and I have checked the price every couple of week since (I know this is potentially a stupid move!) and they have never fallen anywhere close to that low again. The timing for it falls just right so my advice would be to hit the BA sale in December and get your flights then if you want direct. If you're willing to go indirect, use Kayak and check ebookers regularly.
