If you need to get from one side of the ship to the other (Forward to Aft or vice versa) and the Royal Promenade is too crowded, there are stairs down to the casino about halfway down, near the car parked in front of the sports bar. We used that same staircase going up on our way back from dinner, to avoid the crowds going toward the theater.

Do check out the casino even if you don't gamble. The floor at the entrance (from the dining room side) looks like a pinball machine has been built in to it.
