The timing below is a suggested plan. Confirm your venue, supplier, room-release and payment deadlines, and check legal paperwork requirements with the relevant authority.

If our 18-month planning checklist is the essentials view, this is the extended version: every item that ever lands on a destination-wedding plan, grouped into phases. It includes the destination-specific items (passport renewals, vaccinations, welcome bags, guest transport, currency considerations) that shorter checklists leave out.

Print it, screenshot it, or tick it off in a document. Work one phase at a time; none of it needs doing at once.
