Hi Mercedes
We've stayed at the Davy Crocket Ranch a few times - the Sante Fe and some of the others can be cheaper, but the big attraction for me is that the accommodation there is 2 bedroom mobile homes with a leisure complex and huge pool in the main village. This means DD can have a swim, and then go to bed, and I can sit on the porch and drink a nice glass of wine!
Our last trip Sept 2009, cost £321 for 2 adults and 1 child for 3 nights, with 4 days tickets to the parks. We flew, but Easyjet flights from scotland were only about £150 and then another £65 for car hire as you need one at Davy Crocket.
Disney have a weird pricing policy, e.g. you can sometimes arrive a day earlier, and stay an exra night and pay less. If you want a good deal, I think Sep is a good time, as weatehr is still warm, and less crowded too. But the main thing is to look at the deals on the website, eg when they are offering free child places, and then to literally get lots of prices for different dates..
We also went in May last year - and got a simliar good deal - but it was far busier, and the queues were a pain. Over all though, I think Disney is good value, and DD loves it.
Hope you find a good deal - have fun!
They seem to do it to make it max inconvenient, but I now I know it is poss to get a better deal, I just feel determined and sepnd an hour or so playing with different dates.
