For our destination wedding, we invited about 70 people and 38 made it, mostly family and close friends. IMO, it was a the perfect size group. We had always discussed that we wanted to spend quality time with all our guests as they made the time and financial committment to come celebrate us. With our group size, we had time to spend with everyone - some at the beach, at the pool, for breakfast, lunch, dinner, and just drinking & hanging out in the lobby/beach bar in the evening. We even had one evening to spend with just each other with a romantic dinner on the beach as that is also important. If our group was any bigger, we would have difficulty fitting in quality time to spend with everyone. In the end, whoever makes it to your DW are those amazing people who want to share in your happiness and special day! We are having our AHR this weekend and are inviting everyone on the original list including those who made it to Mexico. We have about 60 people who RSVP'ed yes already.
Best wishes everyone
