when i worked for real nationwide-tv, not porn, i sometimes stayed in hotels and took all the equipment with me in the room (because i don't want it to be stolen from the car**) and they never looked at me or asked questions. So, try to make it look, like you are not going to shoot in the room, just as if you are a TV production company and you just stay there. Maybe tell the people at check, that you are a TV producer for whatever station and ask them, what is a good spot in town to shoot.
When we were in London in April, we stayed in a very small hotel, and we shot mostly outsite the hotel, and we always carried the camera outsite very obvious so they always thought, we only shoot outsite. Try to make it like that. And stay in big hotels, so that they will not say anything.
