They are all the same. Its just a matter if you get to the bus stop at the right time. We had long waits at Poly and AKL for the MGM buses, even AK at AKL and you would have thought that was the quickest. To me AllStars has the best, it can be frustrating but at least you see the buses coming and going. At MK waiting for AKL's bus we waited about 25 mins. It was 30 mins prior to MK closing when we got in line (to beat the crowd), it didn't work well.
