Running Out Of Time...help Please

I am recently engaged and getting married soon! My fiance is in the Army and will only be able to come home for 2 weeks so we`re getting married then. The problem is we won`t know an exact date of when the two weeks will start until a month before hand but it will be around the middle of December 06`! Soo, does anyone have ANY ideas at all...?? Or even ideas about somehow incorporating the Army into the wedding?
