I just rang them to book everyone's rooms, and Matt is correct, its payment on checkout, but that is normal prices, ie - £53 on sat, £79 on sun, you need to pay for them now to get them for £43 sat, £64 sun, its called advanced booking.
Daz our are all booked up for the sat night, check in at 3pm, check out 12am on the sunday, includes unlimited continental breakfast.
- your twin room is £43, i have requested a smoking room for you, but they cant guarrentee it, so i've paid for yours until whenever, ok.
