First first three items in your list are included in a special price ticket. Definitely see them all. I have never visited the zoo because I can see animals any time I want back in the states.

Vienna pass saves you loads of money and no need to queue for tickets

I agree with the other answers, and do not know if this is included. Often the palaces are, but the treasuries are an extra charge. We were in Vienna for 4 days, but did not buy any passes, as I found it was better for us to just choose what we really wanted to see, and not feel that we had to get our money's worth out of a pass by spending so much time in museums. This site is so worth a visit, so I encourage you to go regardless.

The treasury is in center City vestido the hofburg palace

да, в любой кассе

No need to pre book. We were there on a busy weekend and there weren't queues at the ticket office. Also, if you get the red Vienna City card you get a discount. This card gives you unlimited public transport on teams, trains and buses for however many days, plus gives you a couple of euro off entry prices to pretty much everything. Our friends had a yellow Vienna city pass and it was very expensive and they found very limited as to which sites you could get into. You can get the red Vienna city card online and then download the app

The website indicates it is closed on Tuesdays. fyi

The Treasury (Schatzkammer) is open every day except Tuesday from 9:00 to 17:30..

E' corretto il mantello è di Ruggero II ma io non ho menzionato alcun sovrano né della casa di Altavilla né tanto meno di Svevia

We really enjoyed the Imperial Treasury. We were not as impressed with watching the Lipizzaner Stallions practice. Maybe one of their shows would be good. Those were the only two sites we toured.
