Come on, leave the jewels in the cassettes and leave Noordeinde Palace. Must éverything be exposed to the public?
The Royal Palace Amsterdam has primarily a museal function, Palace Het Loo in Apeldoorn has primarily a museal function, Palace Soestdijk has primarily a museal function, the former palace at the Lange Voorhout in The Hague is a museum, the former Princessehof in Leeuwarden is a museum, the former Stadtholderly Court in Leeuwarden is a hotel, the Royal Mews are open for visitors.
Only two royal residences have a strictly royal function, one as a private residence (Huis ten Bosch) and as office (Noordeinde). I would say, leave the jewels in the cassettes and leave Noordeinde Palace alone.
