Please remember that all these hotels must retain some semblance of compliance with local health codes and ordinances, and thus must avoid even the appearance of condoning living in the parking lot. That means no slides extended or jacks down, and it should go without saying that chairs, BBQs and the like should remain stowed. As always, they want you to look parked, not camped.
My reading of the 'No overnight parking' status listed on the main Casino Camper web site is that it was an over-reaction by one individual to such a notice. We've seen security drive by multiple times, but so far I have seen no one issued one of the stock notices that they have been putting on RVs for years. We are not alone there have been many rigs with us both nights, and at least one that was here when we passed by two days before that. '.we are currently at the Orleans and have been here for the past two nights.
