There is no Carlson hotel within walking distance of Paddington.
With an 8:30am flight requiring a 7 a.m. arrival to the airport, I can't think of a single good reason why I would spend 70K points (or £150-200+) to stay in central London vs. 28K for the Park Inn or 44K for the Radisson Blu at LHR. (plus the outrageous cost of the Heathrow Express and a taxi to Paddington)
Stay at the airport, drop the bags after arrival and head into London for the day...
