nopoop ...
Spent the first 2 days of my vacation there too.
You have described it to a tee, but I am surprised you didnt notice the other affliction, beside the shorts thing, that most other people in Las Vegas suffer from.
I called it ...
"Walking-around-with-your-head-up-your-ass" disease.
The first day we were there, we were constantly avoiding people who walk around in a trance like state and bump into you and then continue on their way without say they are sorry or excuse me. Well, I started to anticipate their moves and counter with moves to avoid the collision-HO and that worked fine.
The second day, my wife and I are walking hand and hand (I know .. how cute) when some guy wants to walk between us. When I wouldn't let go (wife had no choice) and allow passage he got all huffy and stomped away. That was all I needed ... from that point on, I vowed NOT to avoid any and all collisions-HOs.
Well, by the end of the day I won all (multiple) encounters and two guys ended up on the casino carpet with a very dry ... "OH !!! Excuse me ... you must be suffering from the Walking-around-with-your-head-up-your-ass disease". The wife was a little embarrased but I was having a blast.
I did see the "Blue Man Group" at the Luxor which was outstanding, but beside that ...
Las Vegas ... been there, done that, didn't care to buy the tee shirt.
