Does anyone know of a way to get from Cardiff to London leaving between the hours of say 3am-6am? I live in the US and already made vacation arragements to leave London on the 4th in the morning (around 10:30am). However, i found out about the show afterwards (which is on the 3rd) and am desperately trying to find a way to get back in time to London for my flight. I've already tried to get a later flight and everything is sold out and my only other option is pay another $900/£500 for another flight back home. I've tried the Megabus site, but that doesn't leave until 7:30am and i will not arrive in London in time for my flight. Or are there any other communities or boards i could turn to that might be able to help me out?
