Planning a wedding in three months requires focus and efficiency, starting with prioritizing your budget and guest list to quickly secure a venue, perhaps considering the beautiful options available in Greece such as picturesque chapels or reception venues in Plaka or Litohoro. Booking essential vendors like caterers and photographers should follow immediately, and you may need to simplify some décor elements to meet the tight timeline. Don't hesitate to delegate tasks and consider the invaluable assistance of a wedding planner like Mon Mariage to navigate the process smoothly.
