It is legal to rent a hotel room but if some meth vendor makes a post about how he rented a room out at a specific hotel but the lady at the desk told him he couldn't have a pet stay with him, he shouldn't be surprised if a narcotics officer asks the lady at the counter at the hotel about the man who tried to bring an animal with him. Shitty example, but meh. Measuring things as discrete actions, and thinking they are not risks to your freedom if they are not illegal, is a naive as hell viewpoint to hold. It isn't illegal to post your full name and address here, so why don't you do it , not like you can be arrested FOR it ....course you could get arrested FROM it
