I am flying in to Gatwick airport at around 7pm at night. I need a transfer that will take me to my hotel which is close to Luton airport. Could anyone suggest the quickest/cheapest way for me to travel from Gatwick to Luton (I understand the journey is anywhere from 1.5 - 2 hours). I have looked at northern rail, private transfers and easybus.com. I'm hoping for a direct route which doesn't involve lugging around a heavy suitcase after a long flight at night time.
Suggestions and advice welcome!
