Your question covers a wide range. Wedding is a very casual, creative and interesting activity, combined with solemn ceremony. In my wedding planning experience, I mainly want to know a few points, and then tailor them according to the needs of customers:

Understand the color values that customers like, especially female customers. This is very important, because a color value can represent a feeling, a romance and a special meaning;

Understand the customer's favorite places, such as grass, auditorium, seaside or hotel, and then provide some specific places for customers to choose according to their preferences, and then talk about creativity further;

Understand customers' hobbies, such as animation, movies, photography, sports, etc. And recommend some wedding themes according to customers' hobbies, such as HelloKity theme;

Understand the customer's budget;

Tailored wedding planning.

In fact, a good wedding can only be guaranteed if every wedding of a client is planned as his own wedding. Everyone comes once in his life (excluding remarriage), which is a romantic process for both the married person and the wedding planner. Thank you~
