Found 24th Sep 2016
Email from Premier Inn, stated many rooms £35 and under. Well I had a quick check for Sunday 20 November (Sundays are usually cheapest in any hotel, anywhere), and the St. James Park Westminster hub (new generation) hotel is £37. Same night London Kingston, Kew Bridge, Harrow, Brentford, Uxbridge, Twickenham etc etc are all £29.50. All easy accessible and served by frequent tubes/trains taking under half an hour in many cases from central London.
