Actually many casinos are very beautiful inside, such as Paris, Venetian, and New York New York. So it may be very common for tourists to take pictures inside, and casinos are not against this. For example, I have seen many photos about the lions in MGM. However, casinos might be really unwilling to see photos about people gambling, and they have the right to prevent such photos from being published online.

Hope my understanding is correct.
 My wife and I go to Vegas a lot (went this past weekend, in fact).

 There used to be signs posted that cameras are not allowed on the casino floor, but I did not notice them this past trip.  I'm still not gutsy enough to find out if cameras are no longer officially taboo - casino security has a lot of leeway on the Vegas strip :-)

 My understanding is that yes - you need permission to photograph inside the casino itself as you are taking a picture of private property from private property.  When you capture people in the image, you require model releases from anyone identifiable unless editorial use can be shown, which would be difficult.

 This applies to any private property, to answer your question directly.  I take pictures of the Christmas lights in a couple of neighborhoods every year.  I can take as many pictures of the houses that I want from the sidewalk or public street, but I can not take a picture from a driveway unless I have prior permission from the homeowner (which I get from as many as I can).  I can't sell the images without property releases - I find conflicting opinions, but I'm inclined to believe that any building built recently (last 20 years or so) is automatically covered by copyright.

 I wouldn't recommend selling the images without permission, both from the property owner and from any/all identifiable people.  These images were shot on private property and editorial use does not extend to the commercial sale of the images.

 That's my understanding - I'm not an attorney - your mileage may vary - batteries not included - void where prohibited.

   Anon is correct. & I am really surprised that the casinos even let you
   do them, I am surprised since its not a public but private property
   that you didn't get bounced beat up or arrested.

   You could also be shot. Think about who goes to casinos, stranger things
   have happened

I myself am *very* cautious about how I use photos of people without a
release. I also consider it to be a point of ethics, I ask myself "How would
I want my face used?" YMMV and it obviously does. This is a slippery slope
that I fear to go down without good legal and moral justification.
Good Luck,
me
