I'm waiting for offers for April as that is when we are planning to go for my dad's birthday, failing that October next year. Would love to go June half term but my work have introduced rules that if we take time off during our "relief" weeks we lose our unsocial pay for then and i'm not prepared to let them take my money
They are doing the 50% off now on the UK site (2 days for the price of 4) but you have to book it by the 26th of this month and be prepared to visit by Jan at the latest. I booked over the phone and just paid the 10% deposit, the rest needs to be paid by the 16th november (i think it is).
I have taken advantage of the offer knowing it will be cold etc, but who cares when the parks will be empty and virtually no queuing times. If you can afford to and don't mind the cold, Jan might be a good option for some. You can even have 5 nights for the price of 3 if you so wish.
