Waoh, I didn't think that Luton Airport was that away from London centre !!

It seems that a flight with EasyJet is a bit cheaper than the Eurostar, but then Waterloo-the-shame Station really is in the centre... How much would a come-and-go ticket between Luton and whatever centre tube station cost me ?
Still undecided... Saturday is cheap, but Sunday is not.

And BTW, is there anything going on Sunday ? Dunno where to sleep, but I was actually thinking about enjoying the London night before getting back to the continent early in the morning (7-8 am). What about ?
