I'm not sure what the proper protocol or etiquette is for this. At this point, I am planning to have a meet and greet on a DDB the night before the wedding; since people will be coming from the States and from Australia, and getting in at all different times and locations, I want it known when they RSVP that the meet and greet is happening the night before the ceremony and reception. What is the best way to do this? Should I include a program in the invites that shows the itinerary for those two days? Should I maybe also include a map of Caesar's (where the ceremony and reception are)?
