Capital FM is offering a printable voucher on its website which enables visitors to Thorpe Park to get 2-for-1 on Thorpe Park tickets when donating £1 to charity. The voucher is available from the Capital FM website (registration is required), and can be used until November 7, 2010 (though some dates are excluded).

To take advantage of the offer, print the voucher and take it to the Thorpe Park entrance gate. When buying a full-price adult ticket, a second ticket can be purchased for £1. The park will donate the pound to Capital FM's Help a London Child charity.

Those printing the voucher will also be entered into a draw to win a VIP day out for them up to 10 friends to Thorpe Park.
