My daughter did. They had weekends free and eloped during her A school in San Antonio.
Thank you for posting this!! My fiance and I want to do the same thing.
If you get married, don't move down there until he gets his follow-on orders.
Will she be able to move with him once he has his hard orders for his first duty station?
If the orders were issued as accompanied, then yes. She can move anywhere in the US on her own dime if they miss out on accompanied orders. The only problem would be if he got overseas orders, that is completely different.
