Fair enough. I do read the regular ToS of the hotel that they frame and hang on the wall; it's usually standard stuff and not once I remember reading anything there about use of my data. It's just the usual "hotel night is from X to Y, please don't do <list of ridiculous stuff that some people apparently do in hotels>". So from your comment I assumed that there must be an extra ToS that covers use of personal data. If there is, I've never noticed it.

I don't think there are many hotels handling your personal data except for legal purposes, so they mostly don't need any data policy. So far I've encountered one that simply said that data might be shared with other branches of their company, which I'm happy about.
