I'm sure this has been discussed to death, but I couldn't find anything recent.
The majority of the invitations we sent out to our single friends did not have a plus one. They weren't in relationships when the guest list was created and we're very close to maximum capacity. Now the RSVPs are all coming back with plus ones whom I don't know. I don't care that it's rude- but we may not be able to accommodate these people. If I get enough no's I'm fine with them bringing a date. Is it okay to wait until close to the RSVP cut off date of July 5th before calling them? Or should I call now and just politely inform them that we may not have room?
