Hello all! I'm newly engaged,

and planning a wedding in Cincinnati while my FI is stationed in Italy for the next 3 1/2 years. I was wondering if there were any other military brides planning or have planned a wedding in Cincinnati and what if any advice they offer to me.
I'm struggling with the major things, such as venue, because I won't know his leave dates until sometimes, 4-6 months before the month of July which is when I had planned on us getting married, July 2012. But seeing as they don't even know when they'll get leave in THIS coming July, how do I plan for something NEXT July?
I know I can ask around about military clauses but I don't even have a date to even start with to tell people or book with, it's rather frustrating and I'm sure going to be my biggest pain in planning all of this but such is the military life, I might as well get used to it!
Just wondering if anyone had any advice to offer about places you've used that were flexible, etc.
Thanks!!
