You're making it more of a drama that it needs to be. There will be plenty of folk to chat to. Just go.
@Mightymucks
They’ve been the bigger people by inviting you. If you don’t want to go, fair enough. But if you don’t let the kids go you will look petty in comparison.

Agree with blue just go, otherwise the mil will continue with her 'difficult DIL' story.
All of this. Just go and sit through the ceremony and the meal after, then don't stay long for any night-do. As someone said earlier, this is when shit kicks off anyway.
Just avoid your MIL. She sounds like a trouble-making drama-llama anyway!!!
Whether your niece invited you as an 'olive branch' or out of 'politeness' you are still invited. Trust me, if she didn't want you there at ALL you would not have been invited. There were a few people in my life (a couple I am loosely related to,) who I fucking LOATHE, and they did not get an invite to my wedding.
So your in-laws/niece clearly don't hate you!

GO! And take the kids too. Rise above it all. If you don't go, and refuse the kids to go too, you will proving your MIL right!!!!!!!!
