POS - As many have already said, Titusville is not the most exciting of places. Rockledge wouldn't really be an option either. Best places to live are Port Canaveral (about 20mins to school and right by the beach), Cocoa Beach (a few mins further but, again, right by the beach) or Merritt Island (about 15/20mins to school and 5mins to the beach.
Summerhill Apts are nice but the problem you'll find is that there is nothing around the "neighbourhood".
Best advice I could give you would be to try and get a house with a few other students around Merritt Island/Port Canaveral/Cocoa Beach area. Difficult to organise before you get there but worth it if you can do it. The school should provide you with the contact details of your future classmates so you could email a few of them to see if they're interested in sharing a place.
Final bit of advice is when you attend school to be as professional as possible. You are being watched from the start (in terms of your suitability for a job and for references onwards) and it is important that you keep your head down and show you're working hard. The school has grown over the past couple of years and things may not always run as smoothly as you'd like so you can expect to get p*ssed off at some point but just keep smiling!!!!
