Do you have more tips on traveling within a city? I received a lot of tips on credit cards, airline programs, etc. to use from friends and folks at the company, but not much on local travel...even from home to the airport in Atlanta. By default I'd just get a Breeze/BART/MTA/yada yada cards when I go into a city. I tend to save the reloadable ones from cities I've been to, but many have crappy subways that aren't too useful...so do you have any additional suggestions on rental vs. cabs etc.? In Europe I tend to use cabs but since I go to Paris and London a lot, I use the subways there. I just walk in Milan for the most part. I tend to keep a MARTA card for Atlanta and a MTA card for NYC. I live in the Atlanta burbs so I drive to our airport on the south side of town. The subway can be useful but I find the AC is spotty and the train is slow. I'm too busy for slow subways. It's a good 45 minute ride from the North Springs station to the airport. Plus, my company reimburses $0.52 or so on the mileage. I did leave out one important thing: The Zagat Guide is more or less accurate in every global city I have been in. I buy one for each city.
