As far as third year goes, it's a lottery system for the order of your rotations and the hospitals you do them at. We're affilated with Westchester Med, Our Lady of Mercy in the Bronx, Metropolitan and St. Vincent's in NYC, and Danbury in CT. Those are at least our major affiliations. We've got some others where you can do one or two rotations. It usually works out - trust me, not everyone in your class is going to want to move to the city - it usually works out to about half and half. It worked out for me that the majority of my close friends are still in Westchester! But in the city we've got housing (which is where I'm lucky enough to live) but it's not enough for everyone who moves to the city. The housing is really close to Met (Upper East Side) but not so close to St. Vincent's (downtown) so some students who want to do all the rotations at Vinny's decide to find housing downtown. There's also housing that is run by this woman who only rents to med students. Your rotations could be all at one hospital if you choose that, or you could get a taste of many hospitals and bounce around. All depends on what you want to do in your third year.
