Has anyone ever heard of a lengthy pre-arrival preferences survey?

The other day, I overheard someone saying they stayed at a luxury hotel that requested she fill this out – it asked for things such as her preferred bed sheet color (I suspect this is a highly unusual request of a standard luxury hotel) and what kind of tea (earl grey / darjeeling) she'd prefer.

Granted, it appeared to be a special occasion stay, but it piqued my interest; unfortunately I was unable to get the name of the hotel, so I turn to FlyerTalk for possible answers.
