Would it be tacky to have Santa Clause appear at my Christmas Wedding? ETA

my MIL swears its going to be the tackiest thing ever and I keep  telling her, it's fine. Everyone expects Santa during a Christmas themed wedding. I told her how she doesn't have to sit on his lap if she doesn't want but that's how we're doing it. If she doesn't like it oh well. Now what do you think about it? Is it tacky? I will never admit to her face that i'm doubtful I can pull this off.

ETA: Kids won't be at my wedding. My own kids are 4 mths old so they won't be there either. As of today, MIL is refusing to attend. She can't "suffer" in her words for 5 hrs at this reception. This is her only son! That lady is something else!

I think it's cute. It's your wedding. How does you fiancé feel about it?

Your wedding that's all that matters to be honest. If you want a mall themed wedding go for it.

mid-reception he'll come in and have some guests sit on his lap, he can do some dancing with us on the dancefloor and stay until the end.
