I hire when I'm traveling and prefer outcalls to my hotel. I worry about legal issues and police sting operations. Pretty sure that anyone attempting a sting isn't willing to put themselves at risk coming to my hotel.
Of course, once I know someone I'm comfortable visiting them.
Looking at the issue unemotionally I'm sure I'm taking a greater risk inviting strangers into my hotel room but my concern re legal complications outweighs my fear.
