A: If you rent a car in a wedding company, and your wedding day is a popular holiday or around the year before last, you need to book a wedding car at least one month in advance. If you don't book in advance, you may not be able to rent a good car. Generally, it is recommended that the couple book the wedding car at least 1~2 months in advance. If family and friends at home have enough cars to make wedding cars, just give ten days' notice.
