Really hard to see the academia without having to wait to be entered. I booked ahead of time and I still had to wait more than 30 minutes to enter. The non booked line was worse, that line stretched for miles on a cold and raining day. My suggestion still book ahead, even if you'll be waiting. Also its jam packed, expect to pushed, so hold on tight to your feet and belongings, when seeing David.
