Help! We are having a destination wedding and sent out STDs a long time ago. We are struggling with when to send the invitations because we are inviting everyone to join us on our catamaran excursion if they want to (as an insert to the formal invitation) and want to give everyone plenty of time to book that if they wish before it fills up with other resort guests. Anyone have suggestions on the timeframe? I don't want it to be suuuuuper early, but don't want it to be too late for the excursion booking either. Kind of unconventional, but we thought it was a fun gesture and a catamaran party sounds fun!
