Beating Ryanair on the train
Whilst I agree the TGV is ALWAYS more comfortable than flying (and I take the TGV if I have a choice), 2 hrs London to Paris is not possible. The train time is 2hrs 20mns and you have to be at the London station 40 minutes before the train leaves, so the journey time is three hours.
I regularly travel on the TGV between Perpignan and Paris and leaving at 07:20 I'm eating lunch in Paris at 12:30 - and in France you don't have to be at the station until the actual departure time. First class (big leather reclining armchair) with a standard non-flexi ticket on the TGV costs 40 euros which is MUCH cheaper than Ryanair can offer.
