Centre Parcs - we've never been in school hols before. Anything we need to know?

[roisin]

We're going on Monday for half term break.
When we've been before (weekends in January) it hasn't felt busy or crowded.
Will it feel a lot busier?
Any hints or tips for avoiding queues/busy times/places?
(We have booked some activities for the boys in advance, and the Spa for us of course.)

Been in October half term three times.
It was full to capacity.
If you want to book any more activities do so as soon as you get there otherwise they will all be gone. Swim early (10 ish) or in the evening. We tried to eat at about 6 o'clock otherwise there would be a long wait meaning hungry grumpy children!

thanks
