West End shows are often cheaper than Broadway, it's true, but that's pretty much it. Hotels, food, retail and transportation are all more expensive than anything I paid in the US, even most of NYC.
I did get a great flight deal last year to London on British Airways, though they ripped me off on the hotel promotion by refusing to adhere to
their own rules and regulations. I wrote twice to Customer Service as well as called and they refuse to respond (even though I have several emails from British Airways with case numbers attached stating I will receive a response from a manager). But until someone can find anything that clearly states hotel room "occupancy" is defined by the number of seats purchased on an airplane, I'll be the first to say I was wrong. I always thought hotel room occupancy was the number of occupants in the hotel room, but British Airways insisted I was wrong and told me I was a manipulative liar trying to swindle them (and that was the Supervisor!).
