According to the search results, the percentage of wedding guests who RSVP "yes" can vary depending on factors such as location, whether the guests are mostly local, and whether the wedding is a destination wedding. However, the general consensus seems to be that couples can expect around 80% of their total invited guests to RSVP "yes" to a wedding that doesnt have any special circumstances. Experts say that on average, between 15 and 20 percent of guests will RSVP "no" to a wedding, but this year, couples should be prepared to host as many people as they invite. Other sources suggest that its safe to plan for roughly 15 percent of people to decline the invitation, and more like 20-30 percent for a destination wedding. One source analyzed a set of RSVP responses and found that on average, 83 percent of guests indicated that they were coming to weddings. Its important to note that these are all estimates, and the actual percentage of guests who RSVP "yes" can vary depending on many factors.
