Simple answer yes. They have a cloakroom down a few stairs to the right of the main entrance hall. They will take coats and cases etc as it’s in their interest that you don’t go bounding through the exhibits like the proverbial bull in a China shop! They are also fine for you to pop back and forth to get things, as for example during the Christmas market period they expect you to go get your coat and layers at 11 ish when the market opens right outside between the natural history and art history museums.

si, hay para dejar paraguas y locker para cosas chicas y para cosas grandes hay un guardarropas con numero.

Hi We spent about an hour plus 15 mins for a coffee and bun in the cafe. But we could have spent much longer.

Sommige Musea zijn wel gratis toegankelijk op de 1e zondag van de maand. Maar dit Museum niet ! Met de Vienna Pass kun je er wel zonder (bij) betaling naar binnen. Maar die Vienna Pass is niet gratis, maar maakt wel heel veel toegankelijk en gemakkelijk.

Usually You get tickets at the front desk without a longer line - i agree with the other responders - if no new bus is in front, then you have Your ticket within 5 minutes...

Das weiß ich leider nicht

Don’t know, sorry
