Basics.

Disclaimer: a lot of this is from Let's Go, NFT and other travel guides.  Those folks have already done a lot of the research for you.  Consider checking a travel guide out from the library, or browsing through a few at a bookstore. No need to buy one unless you really want to.

Documentation: Yes, you're going to be in the US, but if you have a passport, you may want to bring a photocopy of it to leave in your dorm room. A photocopy of any official photo id (driver's license, etc) is a great thing to have in your room when you travel, Just In Case.

Transportation: You'll be given an MTA metro card, which was included in your fee for this course. DO NOT LOSE THE CARD. It will not be replaced, and will be expensive to replace out of your own pocket. At some point, you should pick up an MTA map to get a sense of where you can go with your card. Taxis are available for late nights and emergencies, but keep in mind that a cab in NY can get expensive, fast. Don't EVER get into an unmarked cab - only a yellow, licensed NYC taxi. Most of them accept credit cards now.  Always get a receipt (it'll have the taxi ID on it in case you lose something, for example).

Here are some good things to keep in mind in terms of general travel concerns: including dietary restrictions, tips for women hanging out in NYC alone and GLBT travelers.

"I want to go do something fun, but I'm broke."  Good news.  There are always free things to do in New York.  Note that Time Out updates the list daily, so you will always be able to find something free and fun to do.
