what we can do at Port Canaveral Dec. 25th?

Our cruise ship will be at this port Dec 25. This is our first time to be at this port. We need all kinds of ideas of what we can do at this specific day. If not thinking of going to any beach, what else? We are a big group from 6 yo to 50 yo.

Thanks

Rent a van and head to Universal theme park for the day!
