"Amsterdam" - My Wife and I said the same simultaneously. With a few days stay atop a Coffee Shop ... (one would probably not need the Ganja for the exhaust).
Given more thought, I'd hit Vienna first off- see the Performing Spanish Riding School Lipizzaner's show and tour inspect its antiquated work of art-building(s): Winterreitschule. Take the architecture tour also: - (Ref:

Start the day-
take the architecture tour of Wiener Konzerthaus, (Spanish RS) landmark-(Ref:

Take a tour of the Hofburg Palace, next door; afterwards. Get a great bite to eat in an antiquated Dining Hall, ie a street corner hot brat kraut cart....
Vienna's endless with Palace's; classic baroque bliss, and countless wings on everything ...
