This is the checklist we use for a typical destination-wedding client. It covers 18 months of planning from the moment you say "yes" to the weekend itself. Every line has been on a real couple's plan at some point; we have left out the ones that were not.
The order matters. Dates, venue, and planner come first because everything downstream waits on them. Save-the-dates go out fourteen months ahead on a destination timeline, not eight. Guest travel is built into the plan from the start, not bolted on later. If you are reading this with less than twelve months to the date, skip to the Inside 12 months section and start there.
