My wife booked this tour and I was a bit skeptic but was totally won over at the end. Not for kids but my 16 year old found it interesting.

Airport style security checks means you have to allow time to get to the tour check in but during August it was very quick but could imagine with the UN is in full swing it could be a long line.

There is a small cafeteria downstairs if you are early and fancy a coffee etc. Also a nice shop that sells t shirts etc and lots of books for insomniacs
