Exactly, and I will add, most hotels have entrances on the ends of the halls/etc. where you dont have to walk by the front desk. Anytime Im on the road with anything that'd be too big to throw into another bag; I pull up to the front, check in, drop my handbags in the room and then park the truck closest to the nearest exit and carry the long guns in the same way I would any other suitcase. If it's really crowded, sometimes I will wait a little bit just because I dont want any fellow guests taking interest in what I have in the room.I travel with guns often. I bring them all in everywhere. The key is you dont ask and dont look guilty. Just do it.
Not worth the risk to leave them in the car, even in a "best case" scenario where you can park where you can clearly see the truck, with a room on the ground floor near an exit, thieves will be in and out faster than you can get out there to try and stop them, even if you hear them breaking in (short of blasting away through the window of the room of course).
