How can you complain about a free tram??
This is a convenient way to get from Mandalay Bay/Delano to the middle of the strip. From there you can pretty much walk or catch an uber to anywhere else you want to be.
The train comes quickly, there's AC, and again it's free... Zero complaints. If coming from Mandalay Bay, Make sure to get on the second train area so you don't have to stop at Luxor on the way (unless you want to see it), but our goal was to save steps and skip walking through an extra hotel due to the heat.
