Maybe, If I had to have a big wedding. I'd be irritated but I wouldn't discount it and if I did then I'd incorporate it into the day properly so everyone could enjoy it, they are your wedding guests after all. If you can't beat em join 'em, people would simply watch it anyway and possibly not attend, but then I've never wanted a big wedding, just me and the person I'm marrying and immediate family and friends, preferably somewhere natural like a beach or forest, so I can't see that really being anything I have to worry about.
