As Larry states its it your choice. A couple of other things to think about:
If you get them out now, you'll have mom and dad to sit and hold your hand and listen to you gripe for a couple of days about how bad it is, and they can hold your hand and tell you how much they love you.
If you get them out at the academy, you may miss a couple days of classes and possibly some training evolutions. You'll also have a couple of roommates who wont want to listen to you gripe, and most likely will not hold your hand and tell you that they love you.
Again, the choice is yours.. You can see where I'm leaning...
