All this information is so helpful! I took your advice and have done a little research. After printing the subway maps, I printed the bus system maps. Looks like it'll be easy to get around.
Has anybody used the Grayline tours (on/off all day)? Not sure if that's a good deal compared to the city bus and subway.
I'm not a fan of the ritzy stores. Are there any open type flea market areas? I LOVE the homemade type craft places.
