We are addressing the outer envelopes (we don't have inner envelopes) for the invitations and I have three questions:1. Is it ok to address "Mr. John Doe and Guest" on the outer envelope? We have a handful of guests who will be allowed a guest, even though they're not dating anyone. On our reply card, it will say "We have reserved __ seats in your honor" and we will fill in the blank with a 2. Should we just address to "Mr. John Doe" and let the reply card clarify whether or not the invitee gets a guest?2. I know "etiquette" says to list the names of invitees in alphabetical order on two separate lines i.e. Mr. Alan Deer and Ms. Melissa Doebut I've been planning on listing the name of the person with the closer relationship to us (i.e. Melissa Doe is my best friend from high school or a blood relative and Alan Deer is her boyfriend of a year). Do you think, then, that it would be okay to address them:Ms. Melissa Doeand Mr. Alan Deer??? Our wedding invitations are more casual and the wedding itself has a mix of traditional and nontraditional elements. Thanks for your help!
