I eventually plan on using the _ # of seats reserved / _ of _ attending for our RSVPs. We do have a number of single guests (we are not doing +1s, only inviting SO by name). Is it okay to say "we have reserved 1 seat(s) for you"? Obviously this works for 2+ invitees to have the word seats instead of seat(s). I don't want it to seem like we're blatantly pointing out that they are single either - or am I completely over thinking this? Otherwise I could easily order 2 sets of RSVP cards and just fill out the name on the M______ line and remove the seats reserved portion for the single guests.
