If I'm mostly interested in art and design from the Secession period and up until WWII, what are the highest priority museums to visit in Vienna? I've been reading guidebooks, and firstly there are a LOT of museums, and secondly they are quite expensive with no multi-museum pass like you get in Paris or Berlin.
At the moment the following sound as if they have collections I might be interested in:
Albertina
Museum of Applied Art
Belvedere
Leopold Museum
MUMOK
Hofmobiliendepot
Wien Museum
Is it worth paying the fairly high price to get into the Secession building, if whatever exhibition is on at the time doesn't grab me?
