Tons of ups and downs during my 2 night stay during the week when I was in town for work. Vegas during the middle of week is full of conventioneers, conferences, and old people. Well the Palms had its share of older folks or the folks that you won't see typically drop $$$ at the tables but hey it was still nice crowd overall.
Valet was on-point every time except I couldn't call down because of the phone somewhere. When I checked-in they upgraded my room to deluxe rooms on some really high floor of the Fantasy Tower while paying the basic rate.
Down to the casino floor, the vibe was "alive" or as much as it could be for during the week in the middle of winter, the Palms always play great music throughout the casino floor which makes it great because during long stretches at the table you can feel something besides the stack of chips in front of you dwelling down.
