FAST FORWARD TO 2017. I'm about to go back to Luton Airport to visit Georgia. I've decided to take another EASYBUS.
So I went online to www.easybus.co.uk 4 weeks before I left and I got a cheap bus ticket for 1.50 + 50p in debit card fee. Its so much cheaper than a cup of coffee from COSTAS!
Your best best is to buy a ticket after you land that will drop you off at either Marble Arch, Finchley RD, Golders Green. You don't need to do the whole 100 yards to Victoria Coach station.
