We have an RSVP deadline for our destination wedding at the end of February. Some told other guests that they are going to wait to November to see if its cheaper and book last minute. The wedding group rate is already getting $400 off the current price. Although its an all inclusive wedding we have to pay for dinner plates, cocktail reception per person, servers on the day of the wedding and have to provide final numbers months in advance. we are making welcome package kits for each person who has RVSP, personalizing items etc. In addition we are paying for an organized day trip for all our guests off the resort with lunch those numbers I have to provide in advance, private shuttles to resort etc. Most importantly we are selecting the seating arrangements and are doing all the little details such as writing John on seashells with table number. I have a website explaining why we have RSVP and details. If guests show up without RSVP'ing what do you do? How do you handle it?
