Hope Rennie doesn't mind me crashing in on the organising , but I've heard back from Cadbury World. It opens at 10am on 14/3/09 and the prices are Peak rate. We need a minimum of 15 paying people - can be a combination of adults/paying children. So if you've said you're coming, please turn up or we might not get the discounted rates!! Good news though - we don't have to pre-pay, can pay when we get there. We do have to book a tour time though so I've stuck my neck out and provisionally booked this for 12 noon, cos the next available slot isn't until 3.20pm! We can go in any time before that though, and they're open til 5.30pm. Hoping this suits everyone and isn't too early a start for those who've got further to travel!
