For those not doing B2B's at OTP - I have just booked the Vienna House Easy Airport Hotel, which, despite the name, is apparently 0.8 miles from OTP and allegedly has a free airport shuttle. Decent reviews on Expedia and with a midnight arrival and 8am flight back to LHR the next day, I didn't fancy a trek in and out of the City and it's traffic. I grabbed a room for £78 (which is refundable and payable at the hotel) if anybody wants to take a look.
