Our family of 3 is planning on going out to dinner to a nice restaurant. We thought it would be nice to ask some of our friends if they would like to join us for dinner. The restaurant is a destination in itself and is located at a resort. The purpose would be for the company and it would be a fun thing to do. We couldn't figure out a nice way to say join us, but pay for your own dinner/drinks. etc., and would like some suggestions. We don't want there to be any misunderstandings. Thanks!
