People steal a lot of stuff from hotels, and the only purpose it serves is to run up the price for the rest of us. You can take the toiletries, which are likely product placement in every instance. The towels and stuff are another matter.
So are the decorations, even the sculptures.
Check out the security system used with the sculpture. You know it's there because someone somewhere took something similar. I can only imagine what is securing all the art hanging on the walls.
