Just got back from Universal on 19-20 Jan. The biggest tip I can give somebody (if you have more than one day there) is get your wand near close if you want to go through the wand choosing ceremony. In the morning and afternoon the lines were out the door. We went at 6:30 pm, with an 8:00 closing, and walked right into a half-full show on the Studios side. I did make a deal with my daughter that the first day at Universal we would do rides and the second day she could do all the Harry Potter interactive wand spells, etc. So at the end of the first day, we put on her Hufflepuff swag for the show and she got picked for the wand ceremony which was awesome. She was the only under 10 y.o in the room and was easily the most dressed-up which did not hurt her chances. We went to Studios the next day during early admission and, even then, the line was waaaayyy out the door for Olivanders. Seems first thing everybody wants to get a wand; if you can wait till it's dark, it will be much less crowded.
