Not quite as bad an experience as the other Yelpers. They were the first shuttle I saw after baggage claim. Paid $12 roundtrip. Uneventful trip to Caesars Palace.
Pleasant counter lady gave me two gaming chips, one for each ride, no receipt, CASH ONLY.
Return trip to airport was 3:30 a.m. pickup and the driver was on time, courteous and helpful. But he drove Chicago-style.
There was another shuttle from a different company on my return trip that did NOT wait 5 minutes for its fare(s) at Caesars Palace.
