What to do on Dec, 25th?

Hello Houston connoisseurs, we are a family of 4, (children 6 and 8) and are probably spending Dec, 25th in Houston (Downtown).

I've already checked a few places, but I guess everyone deserves their Christmas. Do you know any places and attractions that are open on that day?

For the remainder of the Christmas week, opening hours seem to be normal.

Thank you guys.
