Congrats to you and your daughter!
The best advice that I can give you is to either hire a wedding coordinator for the actual wedding day or ask a close friend or family member for help. As my mother and I realized on my wedding day, you both can’t be hostess to guests and "run the wedding" at the same time. No matter how much careful planning you do, some things may go wrong and it will be better for you if someone else can handle them. You will be more relaxed and have a better time.
My second bit of advice is to listen every time someone gives you advice, say "Wow, what a great idea" and then do what YOU want!
