I am a hotel manager. I have been in the business for about 20 years. I have run independant hotels, chain hotels, cheap hotels and expensive hotels.
If you use your secondary lock (the deadbolt that is part of the electronic lock) housekeepers can not open the door. Normally neither can maintenance. That is standard practice. That is so that a maid doesn't walk in on you in the shower. However, I have a key that will override the deadbolt. There is also one at the front desk. There are usually only a couple at any hotel. It is in case of a medical emergency.
In Colorado a hotel room is a residency, even if only for the night. You can treat it as your home. However, you have to follow the rules just like a rented apartment. No smoking means no smoking. However, if you are not a criminal and I dont have a sign posted prohibiting firearms then you have the right to have one in the room. However, outside the room is another story alltogether.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
