Thanks for the link

I was last there in 2012, and they had them. Be aware they were very long. I want to say it was 3 hrs to get through the palace. So it's very in depth. Possible it has changed since then.

Yes they are still available although I did not use one.

I did the Secret Itineraries tour. If you have any concern about being squished into airless, teeny rooms with 30-plus non-masked travelers skip this for now.
