Just a few random tips related to RSVP cards:
- People frequently send back rsvp cards with just a check for yes or no but don't put their name on it; so you end up with a card and no idea who sent it. To avoid this situation, put a small number or code on the back of the card and keep a list of which numbers went to which invitees; then if one comes back and isn't completed, you'll know who it was.
- People also frequently ignore the RSVP date. With that being the case, you should always pad your date by an extra few weeks if you must provide a number of attendees to any of your venues by a certain date because you might find yourself having to call guests to find out what their answer is.
- There are a couple common annoying things people will do related to RSVP cards, depending on the options that you give them:
- A common thing to put on an RSVP card is a box to indicate number of guests. If you don't want someone to bring whomever they feel like, you shouldn't do this, because inevitably some uncle you haven't seen in ten years will decide his three kids should get a free dinner in Vegas on you and put a 5 down as the number attending.
- To minimize the likelihood of misunderstandings about who specifically is invited, what I recommend is that you address your invitations to the specific people you're inviting. Then, on the RSVP card, do not give them a numbered box, just place two lines, often prefixed by an M (so they can add Mr, Mrs, Miss), so the guest can fill in who they are and who their guest will be, then a Yes or No check box at the bottom to indicate if they are attending or not.
- Although it's certainly not uncommon to not do this, proper etiquette for a destination wedding, and just a generally nice thing to do, is to give a +1 (i.e. & guest) to anyone whom you do not know to be married or in a serious relationship where you'd invite their significant other by name.
- There are a few wedding-related websites that let you do RSVP responses via the web. I would recommend against doing this, and yes I know postage is expensive if you pre-stamp the reply envelopes (which you should do). You can save on postage by using post cards instead of envelopes if needed, but that's the least I'd do. It's not exactly uncommon for websites to screw up and you could lose your entire RSVP list if bad things happen, then you'll be a lot worse off than spending the cost of postage.
