Are invitations to the rehearsal dinner an etiquette necessity? Personally, I will take any excuse to design and print pretty paper, but I'm wondering if people will find it silly since our RD will be pizza and beer in the basement of the church. FI wanted to have it at our favorite specialty pizza/craft beer place downtown, but they can't fit 30 people, so the church has been gracious enough to allow us to bring it into the undercroft. If you got an invitation would you think "you're asking me to RSVP to walking down a flight of stairs?"
FMIL is hosting ours, but since she lives 6 hours away from our wedding location, I'm helping her with a lot of the local legwork. I wanted to have the right answer for her.
