Nothing in the terms to suggest pay at hotel isn't allowed. It states "Reward is provided once the purchase has been verified. Verification will vary but usually takes 90-120 days." So I assume the stay has to complete in 4 months time and this should payout however the booking was paid for.
Thanks, OP. This is looking really good on a £96 Hotel for my trip in August! (y) Any idea as to weather you can reserve and pay at hotel, or is it for immediate payment?

Cheers, had a room booked, re-booked then cancelled the old one.
