So what if you didn’t just go visit a castle somewhere, or even just stayed in a castle-turned-hotel somewhere, but actually stayed in a castle with the royalty who owned it? Now that
would be an experience. It’s basically a different spin on the "bed and
breakfast" idea, where you get to stay in a real castle with servants
and butlers, walk in the gardens, eat in the main hall, admire the
ancient portraits of royals gone before, and then on top you get to
have tea and visit with the lord, knight, or princess that happens to
live there too.
