If you have paid for a hotel room, then isn't the hotel your home for the time in question? I think if you are in a jurisdiction that allows you to posses a gun in your home, then you could posses it in a hotel room.
Not so in North Carolina.
That's my take on it too. Castle Doctrine is in effect when you're in your hotel room. To me, it's no different than being inside your home.
No offense, but your take on it saying Castle Doctrine is in effect when you're in your hotel room is simply your interpretation of a law...unless you can show state statutes saying that's the case.
Don't know about other states, but that isn't the case in North Carolina.
From the North Carolina statutes:
§ 14-415.11. Permit to carry concealed handgun; scope of permit.
(c) Except as provided in G.S. 14-415.27, a permit does not authorize a person to carry a concealed handgun in any of the following:
(8) On any private premises where notice that carrying a concealed handgun is prohibited by the posting of a conspicuous notice or statement by the person in legal possession or control of the premises.
There are other prohibited places, just as there are in other states. I've just shown the one applicable to private premises such as a hotel. It appears this overrides any North Carolina Castle Doctrine type law currently on the books. I don't know that for sure, though. I'm not a licensed attorney, and I don't pretend to be one on an Internet forum.
Taking the "private premises" idea one step further, I don't allow people I don't know to bring a loaded gun, concealed or otherwise, into my home. Period. Do you?
A hotel room, whether you're there for the weekend, a vacation, or a weeks-long seminar or period of instruction is not your home. It is
not your legal residence of record, no matter how hard people try to twist and bend the law ("interpret") to suit their own purposes.
I don't know what the penalties might be for ignoring a "No Guns" sign in North Carolina if someone's found to be carrying. They might just be asked to leave. Or they might be asked to secure their gun in the hotel safe or in their own vehicle, or another off-site location. But if someone refuses whatever request the hotel might make, and if law enforcement becomes involved, I'm pretty sure a judge would be happy to "interpret" the law for someone.
If someone decides to disregard the law, probably be a good idea to stay somewhere that isn't posted and save everyone a lot of trouble.
