I need some advise about RSVPs. We are having our wedding at a ski mountain during the summer, which means that it is pretty dead. Almost all of our guests are coming in from out of town, so we are renting out a bar/band for the night before so everyone has something to do. We are also providing a shuttle service from the hotel to the bar and back for that night.
We are not buying food for everyone that night (only those involved in the rehearsal), but it will be available at the restaurant. The restaurant has asked for a general head count so he can make sure there is enough food available (especially since it's an off-season and he doesn't usually have much available).
My family thinks that I should put it on the RSVP cards for the wedding, which I would normally agree with, but I'm wondering if it is inapprorpiate to ask for an RSVP to something that we aren't paying for. I understand we need to get a head count, and I can't really think of another way. Thoughts? Is this okay?
