I think the people who use kids for sex should be hung by their - ahem - earlobes. As you might imagine, I have  very low regard for pimps and johns. I seriously doubt that any woman would gladly prostitute herself, other than former Slovenian models.... As for hotels, great idea, but a shrug and "we didn't know" is probably all they need to get around it. Just like rental housing, it's stated in the contract that there will be no illegal activity.
