Leave this to the wedding company. Find a better wedding company, they will plan your wedding well. In the process of getting married, both parents didn't play much, so the absence of both parents had no effect on the joy of the wedding.

Of course, now parents of both sides usually change their minds and give red envelopes when they come to power. If they don't participate, the money will be gone.

Also, it is normal for the bride to enter the venue and her father to take her to see the groom. It's a little embarrassing for my father not to attend, but the wedding company will find a way.
