I've carried concealed some places where I shouldn't-that's why it's called concealed. The only place that I would NEVER EVER NO MATTER WHAT carry any type of weapon is to visit a client in a correctional facility or into a federal facility. Several times I have had to do an abrupt about face and leave the line realizing I had forgotten something in my pocket. If there ain't no metal detector and I REALLY feel the need, I'm carrying and if I have to I'll deal with it later. This is NOT legal advice, just an opinion of some schmuck on an internet board.
And as far as hotel rooms are concerned your bigger problem are the cooties on the TV remote, the phone, on the bed covering and on the carpet
Cajun's rule-carry a can of lysol in yo car!
