How many programs are you planning on making? One for each guest, or one per couple/family? I know they are probably going to get thrown out anyway, so I'd rather not make 150 if I don't have to.

Also, both our ceremony and reception are being held at the same venue. They will be switching over the ballroom during the cocktail hour, during which time we'd like the guest to go downstairs to the main floor for drinks and munchies. I'd like to let guests know this somewhere in the program...but where? After the order of events? After the bridal party names? I'm not really sure on how to word it either. I was thinking something along the lines of this:
Immediately following the ceremony, please join us downstairs for cocktails and light refreshments.
TIA!
