BabyPiglet, you got it right

you check-in, and find out your apartment and then you get about an hour to go to your apartment and start moving in. then you have to take a bus (or drive) to Casting and then you stand in loooonnngg lines to finish your paperwork and find out where you will be working.
The first part of check-in goes pretty smoothly but when you get to
Casting, it takes a while so make sure you eat if you can before you go, and be prepared to stand in lines for a while.
Day 2 there is usually a housing meeting that doesn't take very long- they just go over the common-sense rules and ways to act and stuff that will make living here easier for you and the security. Then the rest of your day is free

Day 3 is Traditions- they have actually changed it so now you aren't sitting in a classroom for the whole 4 hours, you actually get to do a little tour of the MK from what I hear (I am not quite sure since I had a Traditions Bypass)
