How do I convince my mother?

to have Christmas at our home next year? We always have it at my grandmother's but we have a larger house... and the crowd is getting larger and are running out of room... we also have a fireplace we can use... I think my parent's house is perfect as we have never really had our entire family over and I would love to play host... what can I say? She hates having people over... even though it's her side of the family and tells them that HE doesn't like having people over even though he loves entertaining people...
