Truly a godsend for all those who want to save a couple dollars on an Uber/lyft or expensive taxi ride.
I love that these trams are air conditioned and frequent as I hate waiting far too long for transportation. If you're going from Mandalay Bay, it'll take you to Luxor and then Excalibur, but if you're coming from Excalibur it will only take you to Mandalay Bay. In order to get to Luxor, you would have to board the train to Excalibur and wait for that stop. If I'm not mistaken, there's also an express tram that will take you to and from Mandalay Bay and Excalibur without stopping at Luxor.
My only gripe is that their operational hours are far too short. Most club goers will leave around 3:00AM and they only stay open Thursday-Sunday until 2:30AM and 12:30AM all other days.
Nonetheless, whenever I do get the chance to board the tram it's always been a seamless and enjoyable one.
