I've booked for 11 nights at PORS in Feb 09 through disney.co.uk I've paid the deposit and have the balance to pay at 8 weeks before trip. Do you know if I could alter the dates or maybe split the stay in 2 resorts rather than just the one. Or could I cancel part of the stay and then book on the US site for the remainer of the stay so I could try and use a discount code to stay a few nights at one of delux resorts? 

I would ring them on the number you book with, I think it's 08702424900 and ask them. You might stand a better chance of getting what you are dreaming of especially with the discounts they are offering at the moment some hotels will soon book up.
