I would never have voluntarily chosen to go on this day, but our family bought Gold Passes at Universal Hollywood from Costco for 2018, and the first use for the passes needs to be no later than Dec. 31st (2017), and there's just no other day we can all make it besides Sat, Dec 30th (probably one of the worst days of the year to visit). I already know that it's best to arrive extra early, but what are some other strategies for dealing with the crowds? Would it be better to avoid the parking garages entirely, and instead take the Metro Red Line and walk up the hill instead of waiting for the shuttle tram? I think we'd like to: take the studio tram tour, walk around Hogsmeade and the Harry Potter ride, see the holiday decorations and some shows if possible. The nighttime show on Hogwarts Castle is also something we'd like to see, but not a deal breaker. We'd be willing to exit the park in the afternoon and come back for the nighttime show, but I'm afraid the park might close because it is at capacity. I'd appreciate any general or specific advice on how to best manage visiting that day. Thanks in advance!
