This whole of December I've plan to visit Universal Studios every week. USS is currently having their Santa All-Star Christmas from Dec 1st till Jan 3rd 2016. The park is open from 10 am to 9pm daily and they have a cheaper price ticket of $48 for entrance on 5pm onwards. All rides are open and on certain days there will be fireworks. The fireworks are really amazing.
I will update my Christmas adventure at USS once I've got all the picture water marked.
