The spsg tickets site offer two options for Sans Souci +:
sanssouci+ Online Erwachsene (EUR 21.00)
sanssouci+ Online ermäßigt (EUR 16.00)
But I can't make sense of any. Not with Google, not with a german-speaking friend.
So, what ticket should I buy, being a colombian tourist, visiting Potsdam and all I can of Sans Souci park and buildings in one day?
Thanks in advance.
