What is the best plan for New Year's Eve at Disney if you don't have a park pass for that day and you have a 13 year old and 18 year old and you want to celebrate at midnight? Disney Springs? Doesn't it close at 11:30pm?
I would check to see if your hotel is doing anything or consider something in City Walk at Uni. There is no way I would drive from the Universal area to DS on NYE.
