In town for a national conference and should have taken a tour before Saturday as there was an hour and a half wait out in the sun on Saturday around noon (versus very little or no wait earlier in the week).
So I didn't take the tour.
I visited the gift shop which was awesome and then waited in line for 30 minutes to check out (TONS of people were in line and it actually moved pretty quick)
