I want to add, since I wasnt thinking about them at the time, that Non-smoking rooms are bad. They usually have either a special smoke detector that can't be tampered with which goes off if plant material of any sort is burned, or some other feature in place to make it resoundingly obvious if you've smoked at all in the room. The reason is that vicious or campaigning anti-smoking people, as well as a percentage of the normal population, are very acute at detecting tobacco smells in a room and will complain if they do. The hotel has to cover it's own ass and charge you for the cleaning if you light up in the room. True, they're thinking about cigarettes and not weed, but I'm sure weed smoke would trip any safeguard that tobacco smoke would. Be very wary of designated non-smoking rooms.
