I agree with a lot of the other posters on here about the inconvenience of the monorail. It seems to zig zag around a lot of the hotels and still leaves you a ways from your destination. Maybe it was the only option when they built it: don't let it block the casinos from adding more hotel rooms or other buildings if they wanted to in the future. I don't know. But you seriously have to slog it through casino after casino to get to the station. It sucks if you're staying at Excalibur or NY NY. The closest station is MGM Grand. You still have to hoof it through MGM to find the station. The signs can be deceiving in the casino.
Taking cabs or just walking straight up or down the Strip can get you to where you want to go in the same amount of time. Too bad all the conventioners hear about a monorail, buy tickets and then leave. The monorail makes its money and keeps on running. I wonder if people will catch on eventually and not use it as much. It wasn't ever that full even during the massive convention I was at.
