Thanks. That is an interesting article. It clears up certain points for me, including the criminal trespass issue. If the law specifically exempts the hotel from needing the eviction order (which is my wording of what it said in legalese), then the criminal trespass issue is valid. All it takes is the management to tell you to leave the property and you would be guilty of criminal trespass when you refused to leave.
The bad news is that the author, who is a lawyer but not my lawyer, explains that the hotel room is not treated as an extension of your residence. By specifically saying a rental of a hotel room is a license to use the room in accordance with the hotel's rules, it means the 30.06 warning does apply to us when we rent rooms. I would recommend avoiding all hotels where there is a 30.06 sign to be safe now, and not just because I disagree with their politics (posting against guns).
First off, IANAL. That said....
I am not sure that the interpretation of a hotel room not being an extension of your residence for certain purposes automatically means that 30.06 signs are applicable while you are in your room. But even if that is the case, I would note that 30.06 only applies to the carry of a concealed handgun by an LTC holder. It does not impact the ability of a non-LTC holder to possess a handgun while in their rented hotel room. That would be allowed under the travelling provision per Texas law. Since you are legally able to possess the gun while in your room, without availing yourself of your rights as an LTC holder, then it brings up that old question of whether an LTC holder is always carrying under the authority of their LTC, which, if true would make criminals out of any LEO's who have an LTC and who carry a concealed gun into a 30.06 posted location while they are off duty.
But even granting the above, it is important to note that the 30.06 provision still would not apply to open carry while in your room, or to storing the handgun in the room safe, etc. I guess you could be safe and put your gun in a locked box within a suitcase then have the bell hop bring your suitcase to your room (let's hope for his sake that the bell hop does not have an LTC, I guess). While in your room, either lock the gun in the room safe or carry it openly. Note that I doubt that carrying the gun in a locked box within your suitcase would meet the definition of "carrying" per 30.06 in the first place, which would save the poor bell hop, or you (if you choose to carry your own bags) from the remote possibility of $200 fine.
