My Fiancee's family has already stated that there may be issues with certain people only attending the ceremony due to mobility issues as well has memory problems for the more elderly side of his family. Is it rude to put on our RSVPs if they can only attend the ceremony, only attend reception, or both? We also have lots of couples with kids and it's a kid free wedding so we know some may have trouble with finding a sitter. There will also be a gap between ceremony and reception of about an hour and a half maybe less for pictures because we are not doing a first look.
