My fiance and I have compromised our ideas for an engagement party into a big backyard BBQ; late afternoon to dinner with family, dinner to evening with friends. We want everyone to meet and mingle, but we can't deny that our older relatives aren't interested in the same kind of party as our college buddies. What we want to know is if there is any etiquette in sending out invitations to a party of this type. Should we send paper invitations to our older relatives and use facebook for the younger crowd? Should we send mail to everyone? Should we just rely on a phone call? Some of our guests are travelling from out of town, so should they recieve something different? This party is so much less formal than our actual wedding, but I don't want to accidentally offend anyone a whole year in advance!
Thanks for the advice!
