Three more words - 22 Dollar Tuesdays!! 2 adult tickets, 1 large popcorn, 2 large drinks = $22.
Located inside the Palms, this theater is a great way to kill some time if you're in the area. Boasting 14 theaters including IMAX and IMAX 3D, you can easily forget that you're inside a hotel/casino. Cushy high back rocker chairs make seating comfortable. The seating here is not assigned, it's first come first serve but unless weekdays that's not usually a problem.
Over the years I've seen many shows here, the latest was Iron Man 3. They have digital sound and wall to wall curved screens so even the smaller theaters are nice and an enjoyable experience.
They are located right inside the food court at the Palms, I wish they would let you bring your lunch/dinner in, but no luck.
Tip: if you have players points with the hotel you can exchange them for value towards your ticket or food purchases. It's a nice extra perk.
