Well I actually live in Thornton Heath so you're luckily enough to have the best Melee player in the UK living near you and someone who is decent at brawl even though I don't really play it
To answer your earlier question, the tournaments are alright...nothing too special, you're a brawler so you can complain about their stage choices....'That snake stage with the walls is allowed but Rainbow Rides banned

' and also you're only allowed to pick one character for the whole tournament....like you actually can't counterpick, it's gay
BUTTT I will actually be there so I can also direct you, but basically when you get to East Croydon you cross the road and get on '466' literally one stop and then you get off and walk. You could actually walk it from there but you dont know the direction
