I have the feeling that the Casino Royale promo could make even their shitty video poker +EV, but of course, that depends on exactly what the rules are. Do you have any details?
During my visit a couple of weeks ago, I also noticed that people were quite friendly...except for the 65,000 or so drunken louts who weren't. The actual friendly people were casino and restaurant staff, who were no doubt happy for the illusion of things being back to normal and covid having disappeared completely, at a wave of the casinos' magic wand.
I did observe a lot fewer people than usual smoking, which, given that Vegas is Stink-Stick City, was probably due to small sample size. Mask wearing, though still mandated at the time, was well below 25%. And yeah, people were partying like it was 2019. Everyone was paying the high prices and fading the high limits. Even the dust joints had $25 table minimums. While I stuck to my usual pattern of coupons and deals for my meals, it looked like just about all the restaurants had increased their prices 20-30%.
Vegas will be fun this summer, but woooo hoooo...bring money. Lots and lotsa money.
