I have been to the showroom at the Orleans Hotel and Casino probably 15 times. This 850 seat venue has theatre style seating as opposed to the classic Las Vegas showroom consisting of booths and tables.
The staff at the theatre are always very helpful. Sight lines from anywhere are good although I prefer the three center sections BB, CC, or DD rather than stage right AA or stage left EE.
There are cup holders attached to the seats in front of you, but it can be a bit of a reach as the legroom in the aisles in excellent.
The showroom tends to have entertainment that appeals to the older crowd such as tonight which was a 90 minute show by the show business legend Mitzi Gaynor who at 80 years of age put on a great show.
The lighting is well done, and I have never been here when there wasn't anything but the best sound levels with no microphone problems.
