Step 1: Hire a local wedding planner
This is the single most important decision you will make in the wedding process and, while obviously not mandatory, there are so many hoops to jump through we don’t recommend going it alone. Remember, you're planning a wedding in a location (possibly) thousands of miles away. And, most likely, over email and by phone. With people for whom, in most cases, English is not their first language. So yeah.
Where to start? If you don’t know any local wedding planners (and we assume you do not), Google "wedding planners [insert your city, country of choice here]," contact a few for pricing, and choose. Seriously, even with a planner to rent the wedding hall, book the hotel (in our case, an apartment on Lake Como nowhere near Clooney), hire the photographer, pick up flowers, assist with paperwork, arrange your sweet-ass tux, and take care of any post-wedding parties or celebrations, it's still a surprisingly arduous undertaking. As you're about to find out.
