I'm looking to book for a day during our December trip to Universal. I'm thinking 12/10 and if the weather is funky, we'll have the 16th or 17th as back-up days. Still working out the schedule with my son's finals' schedule at college, but I hope to have it booked by this time next month. Very excited and as it's our first time going to DC and it will be a surprise for him until the morning of.
