From Bob Atkins Photography:
If you are on private property, such as in a store, shopping mall, sports arena or theater, then you need permission from the property owner to photograph. If you take pictures against instructions not to do so then the property owner has the right to ask you to stop and/or to leave. If you refuse, you can be arrested for trespass. However the simple act of taking a photograph there isn't illegal and you do not have to surrender your camera, your film or memory card and you do not have to show your images to any security personnel or delete your images. You can simply leave the area if told that photography isn't allowed.
If it's just in the suite and it's just for personal hobby, I would say go for it.
And even if it's not just in the suite (lobby, etc.), I've personally taken pictures casually of friends and families at a hotel so I don't see what the problem would be. Just don't start taking out your entire studio set with 3 umbrellas and a reflector.
All in all, I would say just use a good, common-sense judgment and if asked to stop, just simply stop.
