We're a group flying in to Luton on Friday 6th June at 8:10. We originally planned on using a car service but have since scrapped that idea. There are 5 adults and 1 child. Can anyone recommend the cheapest and easiest way to get from Luton airport in to central london?! The train was coming in at silly money, easy bus is obviously a no go (but checked and was £20 per person! For a shady service, you can see why this is ridic!) I also checked Greenline and it wasn't too bad, £15 open return per adult, but seemed to take A LONG TIME. I can vaguely remember someone posting about using the train in a group you can get a discount but I can't remember exactly! Any help is greatly appreciated!!
