I stayed at the Four Seasons for 2 nights on a recent business trip.
the good:
the most awesomely comfortable beds in Vegas
great, friendly, helpful service
they like to give you bottled water
evening room turn down
private entrance
no smoke
relaxed and quiet
the bad:
no self parking and valet is $22/ night
hearing barking dog in nearby room
long walk to/from elevators and to/from everything else!
hearing barking dog in nearby room
The Verandah restaurant sucks
did I mention they allow barking dogs??
I love dogs, but they belong in a strip hotel about as much as a newborn baby does.
