I would be PLEASED to pay under 100 pound!!!
The cheapest at Paddington is 161 pound and the Metropole is 153 pound(that is certainly not worth over 100!!)
The airport hilton is 150 pound(I need an early departure so need to be close to airport.
I did see the Kensington at 62 pound which is a steal but too far away for a 9am int dep.
