Have you and your husband considered him taking your surname? If not, why not? If this isn't something he would ever contemplate doing, it's worth questioning the assumption that you will take his.
Every woman who keeps her own name and every man who changes his is helping to combat this automatic assumption that women's identities are less important than men's.
As a woman who didn't change her name on marriage, I can tell you about the pros and cons.
Pros:
I didn't have to change my name on any documents/email addresses/accounts etc. This is a huge plus! Fuck doing all that admin.
I feel like I have kept my own identity and it hasn't been erased in favour of a man's just because patriarchy.
My name still sounds just as good as it did on the day I was born when my parents made sure it didn't sound silly or spell anything rude.
Cons:
After I got married some people assumed I had changed my name and sent stuff to me as Mrs Husband's name. One thing got delivered to the Post Office and I didn't have any ID in that name which was a pain.
I don't have the same surname as my children. This doesn't really bother me because my son has a variant of my surname as his first name and my daughter has the same middle name as me. I haven't travelled abroad with them and without their dad yet but if I did I'd bring copies of their birth certificates and a letter signed by my husband. I don't think this is really a big deal.
