I'm so sorry but the answer is NO.... if you have not RSVP by the deadline that will just be one less person.
If there is no plus ones for you, you will not be allowed to bring anyone else, SORRY!!!
If your name is not listed you are not on the guest list, please do not take it personal we wanted to invite all our friends and family but spacing is limited.
When you find out immediately contact either the bride or the groom so they are aware.
Yes you will but there will be a special area for all gifts to be station.
