Okay, always very happy to learn something. I don't live in NYC, although I did grow up there and am there 7-8 times a year. I'm pretty familar with London too...there about once a year. I think 1.5-2x is about right. I haven't been to Paris and Tokyo in 4-5 years, but I remember them being even more expensive than London (especially Tokyo). What do you think is a better ratio? TIA.
