As with most things, it depends on your use case. The MGM station is the easiest one to get to, as some of the other stations (Harrah's in particular) are buried behind the hotels. There is a dedicated station at the convention center, which is great for thousands of people if they stay at one of the hotels with a station. For example, a person attending a convention at the convention center and staying at MGM - normally a $30+ cab ride each way - can get essentially door-to-door transportation both ways for 3 days for the price of a single one-way cab ride. If you're staying at Wynn/Encore or Venetian/Palazzo, then it's not going to work. But since you're paying $400+/night there during busy times at any of those places, you might as well rent yourself a limo. The monorail is OK for some use cases.
