/kloc-one table for 0/0 people, 300 people in your family, that's 30 tables, even if there are so many men, that's 60 tables.
Now many hotels can handle more than 50 tables.
If there's anything wrong, it's a hall with a box. It needs to be solved at one time, which is both lively and convenient. Doing it twice is really troublesome.
If you have a wedding reception, you should spend half a day watching the hotel with your husband or family.
The hotel must see for itself how big the hall is. I'll know this by myself.
As for the layout of the hotel, the host, etc., you can give it to the wedding company, and they will help you decorate it beautifully. There will be no regrets.
