Okay, let's start with the fact that this is still a civilian forum. Dates in the format 20070306, are hard for us sand crabs to read.
Second, the military does not write dates like that either. You'll either write 06Mar2007 or something similar.
Last, and most importantly, NOTHING in the Navy is just like anything that is not in the Navy. Therefore the statement that "A" school is pretty much like normal college is not completely accurate. College students mostly do not wear uniforms, get inspected in those uniforms, have barracks inspections, clean the floors and toilets in the school, start classes at 7 a. m. or stand fire and security type watches at all hours of the night (Christmas and weekends included). You may have no classes scheduled on weekends, but that doesn't mean that your time will be your own. Civilian visitors will almost certainly be prohibited from your quarters at certain times. You will not be allowed to entertain members of the opposite sex in your room during most - if not all - hours.
However, if a weekend happens along when you have no duty day, and you are otherwise unencumbered by your military obligations (change of command ceremonies and stuff like that are almost always held on Saturdays, and attendance is mandatory for all hands), you will mostly have liberty. When you are on liberty, you may go out into town and visit your friends at a hotel, maybe bring them back for a short tour of your base, have meals with them, drink (if you are old enough) and party in the bars til ungodly hours, and pretty much behave as if you were a real human being.
My advice is to get your duty schedule and check if your are going to be free for a particular weekend before you invite anyone. Still, the only way to be sure that you will be totally free on any given weekend is to be on leave. Leaves are rarely cancelled unless an emergency comes up, but school commands almost never grant leave to students.
Get boot camp behind you before you start looking beyond that. You will learn the specific rules of each command as soon as you get there.
