I'm with bitterpoetry. Your wedding is your day. I find bizarre the whole idea that a guest might feel entitled take umbrage at pretty much anything a couple could choose to do at their wedding this side of hiring strippers for the entertainment. Let alone feel insulted. (And in my book they're only entitled to take umbrage at the strippers if the invitations failed to warn that the entertainment would likely be unsuitable for small children.)
In short: relax. It's your wedding, you're the only one it has to make happy. The guests' enjoyment is rooted in yours. Don't fret about them.
