My fiance and I are already footing the entire bill for our wedding. We would like to have a rehearsal dinner, but can't afford it and our parents aren't willing to pay for it either. What wording can we use to invite individuals to the rehearsal dinner, but tell them they have to pay for themselves?

I appreciate the good (and the snark) comments that I received. We spoke with some friends and decided that after our morning wedding rehearsal that we will head to a lunch with 20 guests. Everyone participating has already let us know that they are okay to pay for their own meal. So, IT WORKS OUT!
