Despite differences m decoration and price, one thing most hotels have in common is a set of rules. Failure to obey these rules can result in fees or fines to cover hotel room damages, removal from the hotel or possibly even arrest. Smoking Some hotels are completely non-smoking. Some hotels designate smoking and non-smoking rooms. If you smoke in a non-smoking room, you will likely be fined hundreds of dollars and possibly asked to leave. Number of Guests Most regular hotel rooms are designed for two adults. If you have more than two people staying in the room, the hotel will likely charge an additional fee for each extra guest, though some hotels let children stay free. Do not put more than four adults in the room unless the hotels policy permits that many people. Or you might be fined or removed from the hotel Hotel Reservations Requirements Most hotels require a major credit card to reserve the room. You can pay cash at the end of your stay, but do not be surprised if there is a temporary charge on your card for a few days after your stay. Most hotels authorize a security deposit on your card to cover any possible damages to the room. Once the hotel confirms that the room is undamaged and that you do not break any hotel policies, your security deposit will be refunded. Breaking the Law You cannot break the law in your hotel room, just as you cannot break the law in your own home or in public. Do not do drugs or commit any other criminal act in the hotel room. If you do, you will likely be arrested. Noise Most hotels have a noise policy you must obey. If you are being too loud you will usually get a warning. If the noise continues and more complaints are issued, you will likely be kicked out of the hotel, regardless of what time it is. 21.
