Everyone in my class is taking the entire standdown for leave. We are all going negative on our leave days. I have two shipmates in my class that are getting married over the break. Also, it is true that you cannot drive during phase 1 of training, but if you are on leave, the phase restrictions are not in effect, therefore, you will be able to drive and wear civilian clothes, and drink if you are of age to do so. If there are any other questions, your fiance should ask her SLPO. That is the best way to get 100% accurate information on current policies and their final word.
