I am having a small wedding and reception (40-50 ppl) at the same location. Most of the guests are ppl that we have both known for 20+ years and I am sure they don't really know a lot about proper wedding etiquette. I am about to order my invitations and i have always just thought i put the event time ,however after reading some posts on here i am not sure now if i put arrival time or ceremony start time. I do know that a few of these ppl are known for always being late so now i am second guessing this.
