Quick report from today...
It was freeeezing today - did early entry (at 7am this week), short Olivanders wait, walked on to FJ, & hippogryph. Dueling Dragons was the longest wait - shops mobbed by the time we were done, with lines to get in. When we left the FJ line was way way out.
Went back later (about 730pm), and the area was much emptier - walked onto FJ again, shops were much easier to get around in, and the Olivanders line was very short.
Won't do early entry tomorrow, but will go back late evening for more nighttime pictures and a little shopping.
