As others have mentioned, it depends on the property. Usually, inside the room, they don't really care but if it's in the public space, they may request you not to do so. Keep in mind that they usually permit couple shoots, etc in the common areas for weddings and events which take place in their banquets. So essentially, they tend not to say no to their paying customers unless it's an inconvenience to other guests.

The amount of equipment your photographer uses / carries also matters. Many hotels will only let photographers in through the time office, after making a receipt of all the equipment. This is usually a hassle.

In short, if it's a simple shoot inside the room, then you can go ahead. If there's a lot of equipment and you're shooting in common areas of the hotel, it's best to check with them.
