I was surprised that the monorail was really dead. A bought a discounted 3 day pass and used it a few times to barely make it worth it. I think the problem is that the monorail is set so far back from the properties that once you've walked there, you could've been half-way up the strip already.
We also rode the free tram from Bellagio to Monte Carlo (which they didn't have the last time I was there) and that had kind of the same problem - but at least it was free.
Thinking next time I'll just take cabs if I need to save time or rest my feet. Curious if other people jump on the buses?
