France wedding Q’s

Hiya!


We’re going to be booking our wedding for Sept 2026 and are in the very early stages.
We’re also renovating our house, which is using up a lot of our money at the moment. Meaning, we’re trying to book our wedding on a bit of a budget and are yet to decide if we can have guests or not.
I’d much rather have guests than spend on a wedding planner, but does anyone know if they are absolutely necessary? Can I not just find suppliers myself, or is there much more involved that makes it more valid?
Ideally, we’d like to get married in either Nice, Antibes, Le Cannet or Bealieau Sur Mer! So also open to any generic suggestions people might have 🥰
Thank you!!
