I had a great trip on October 22, 2017! Scheduled to leave Las Vegas at 10:15 PM, bus rolled in 5 minutes earlier. The driver was very professional as he handled a couple of customer challenges which arose at the pickup area, then we were on our way. Two hours into the trip I passed out and awoke, an hour later, at a rest stop . Fell back asleep and an hour and forty five minutes later I was in downtown L.A., 15 minutes ahead of schedule.
The only downside was being dropped off in a sketchy area. Downtown L.A. is loaded with homeless people at 2:45am. I didn't have any problems, as I stood there alone with my suitcase waiting for my Uber, but you might want to keep that in mind.
