This may be a little embarrassing, but here goes:
1) As I understand it one shouldn't use the ATMs (Travelex) at LHR; instead, wait until you get to a bank ATM, like Paddington Station or downtown, etc. Which "bank" ATM is recommended? Any of them?
2) Which side of the street for the bus? If memory serves me correctly there is a sign indicating which way the bus is going. If you recall I'm the guy who not once, but three times, took the Metro in the wrong direction before figuring out where the hell I was.
3) Do contactless credit cards work equally well on the tube, bus and local trains, like Victoria to Gipsy Hill?
4) When using the TFL planner, or city mapper, Emma and others have mentioned the travel time as optimistic. How much time should one add to what TFL indicates? 15 minutes? 30?
If anyone wants to piggyback with random questions that's fine with me.
