Thanks for sharing. My official review is "meh".
I stayed at the Las Vegas Club last month. There are lots more details in my report, but to make a very long story short...
a) the room was fine, but...
b) they were down to one elevator, which was as bad as you think it might have been.
The $20 trick will probably work to get you in the better tower, but the same bill would buy two more nights here or another night somewhere else. You make the call.
P.S. No Fridays or Saturdays; those are more expensive.
