I would say the Island is a good bet.....if you get a roomate. At first I was worried about the comute because of the construction....but it really is not bad at all. Get a couple of guys and find a house or townhouse to rent, it will be worth it for the time you are here, especially if you are burned out on Apartments from college.
I think your best bet for a roomate is to find someone in your API class(or at API in general) to move in with once you get down here. but choose you roomate wisely....I almost roomed with a guy who Failed out.....(meaning, he/she will not help you study!). Try and find someone motiviated about the program.....
If you still needing a roomate when you get down here, just start talking to people, chances are they know someone who needs a roomate as well. I would not live alone for several reasons.....first, because you need to get the gouge.....if your roomate is a couple of weeks ahead of you, you can get pretty good gouge from them.
Secondly, you should not be a hermit, or you will hate life down here. Going out and having fun is part of the experiance (but know why you are here, to train, not to party, and limit it to Friday and/or Sat. only!). Finially, it's cheaper.
