Hotels are tricky things and they (management/security) tend not to know that your rights change when you are staying in one. In Nevada, your hotel room is now considered to be an extension of your home in the eyes of the law. Legally speaking, they cannot stop you from going to or coming from your new temporary residence, however they can ask that while you are using their amenities outside you hotel room that you secure your firearm either in your room or in the house lockup. While you are passing through the casino floor on your way to your room, take the most direct route to your room the exit without lingering. If noticed by security and they question you, explain that you are on your way to your room or on your way off the property. YOU CAN NOT BE KICKED OUT OF THE HOTEL FOR BEING ARMED!
