My fiance and I are private with our emotions and affection for one another - we don't engagement in very much verbal/phyisical PDA.
We like the idea of saying our written vows to one another without microphones. There are things that we'd like to say that we don't want to broadcast to our 200 guests, many of whom we don't know. If our vows are short, maybe 30 seconds per person, would this be okay?
ETA: Our parents insisted on a larger wedding than we wanted. Paying for our own wedding to be able to have a more intimate crowd is not an option - STDs have been sent.
