FYI..
Just a reminder: when the power goes out (and it does) that means ATM machines wont work- also , many times they are out of cash (esp sunday) and ATMS can eat cards too....You will not got it back-or not without an insane amount of time and hassle...I rec. everyone have two separate cards if using ATM (if one gets lost, etc) alwasy have some emergency cash stashed and its a good idea to have a few Travlers cheques for back-up ..if you lose them at least you can get them replaced in a timely manner..Not so with cash or ATM/credit cards...
Also- for the most part do not carry your passport around-leave in safe place and make a good -color photocopy to have with you at all times and write on there where your staying and emergency contact number..In case something happens to you (and you cant respond) they will at least know who you are..
I also write down the phone of the us embassy-in case a have an emergency and need their help...all this just takes a few minutes and just a simple piece of folded up paper you take with you...
Other than that-my jam cell-and my little port i=pod for music...I travel as light as I can..
