If you go to orleanscasino.com to make a reservation right now, they're showing the hotel is sold out for Friday and Saturday nights.
If you go to Vegas.com or Orbitz.com, however, you can still get a room and at a good rate, too.
The Palms still has rooms available, but they're $250+ if you're not getting a special rate. I may need to stay there Saturday myself, though.
