From there, it’s less than 2/10 of a mile walk North, past the Casino Royale to the front doors of the Venetian. To get to the Venetian, you’ll want to get off at the Harrah’s/Quad Station and walk through Harrah’s (inside) to the Strip. The monorail is air-conditioned and smooth and offers a great view of the strip.
You can buy your passes very easily there too. The nice thing about staying at the MGM Grand is that there is a monorail station onsite (it’s on the east side of the resort, on the opposite side of the Strip).
