I am writing a book. I have done research but it is still not clear for me. Can I use the names of the Las Vegas hotels/casinos in my book? The story is (in the chapter that involves them) a fire bursts out in the Luxor and the characters escape to the Mandalay Bay. One character turns to demon and chases the other character through the Mandalay Bay and into the damaged Luxor. They visit the other casinos (names might be mentioned). Can I use the names of the casinos? I heard that the company might not like it if I use the name of the Luxor with the fire. So can I use the Luxor and the names of the other casinos or do I have to make up names for them?
