Got 4 nights of a comp room at Caesars. Unless you upgrade they put you in the Centurion Tower, which is the older but renovated tower.
The room was pretty large as it fit two beds and a couch. No desk. The bath was huge though - the size of a studio apartment in New York City. No ice machines in this tower so whenever you wanted ice you had to call room service and they would wheel it up. If you stay in this tower, do not stay on floors 30-32 (the first 3 floors in this tower). The tower sits right above Cleopatra's Barge (nightclub) and multiple people had told us that the could hear the club into the wee hours of the morning.
The pool at Caesars consists of 3 pool areas. The pool bar is long, there are in pool blackjack tables, and massive beds at poolside that you can rent for $200 a day. The chair area is cramped and get there early to grab chairs. The sun also hits the pool at a weird angle, so only half the pool gets sun. The hot tub is the size of a small pool.
All in all it was a good stay. But who is to complain since the room was free?
