I'll fly in via Stansted then I'll sleep somwere in that area (dun know the adress yet though) at another ENBoarders place.
I'll come in on Saturday around 5pm, but I will not meet up with my buddy until arond 10pm so I have some time to kill that evening if you have nothing else to do (will try and gather up a bunch of people for this so it will be more fun for everyone).
Never been to London, but it will be an experience to find my way around there
