I concur with Roberts post. I would encourage him to elaborate on his definition of "a few" because I recall that not being the case on several occasions. The Porch!!!
The TV was about 13 inches in "The Disco" (the name for our apartment because of the 1970's furniture and carpet). Internet can be purchased, but most peoples apartment could pick up a neighbors wireless connection. Also, there is always a wireless connection at the school (at least in Riverside).
First word of advice would be to keep the place clean.
The people that went right from living with a parent who cleaned up their mess everyday had a problem adjusting to life with 3 other people in a 2 bedroom apartment. There is nothing that makes you more bitter then coming home from a 6 hour night XC and seeing a sink full of dishes and the trash can overflowing.
ATP is what you make of it. If you lock yourself in your room at night and don't interact with everyone, you will have LOOONG 90 days. The first few days are a bit awkward because you are coming into an environment, that at times, is almost like a family. I will know the guys from ATP for the rest of my life, I am certain of it.
Just be yourself, and don't try to impress people with stupid things that mean nothing when you get in a Seminole. I don't care that you were the smartest kid in your PPL class and you gave the best oral answers the examiner had heard in his 45 years of being a DE, or that you have 500 hours and your daddy is a GV pilot.
I care that you are a nice person, clean up after yourself, understand that sometimes the apartment needs to be quiet for studying, and that you carry your weight in the cockpit.
And the second word of advice, don't be one of those guys that rubs it in everyone's face that "he has a job waiting for him when he gets done the 90-day program."
Just my two cents..
PS: Always lock your doors.
