Let me point out that "going through the tunnel" is not always wrong. If you are staying at Tahiti Village, Worldmark on the Blvd., Cancun or Grandview, it would be the way to go. It would also be a fast way to the resorts out near Tropicana, ie., Tahiti, Westgate, and I forget the other one. It is also the way to go to Cliffs at Peace Canyon.
But it is NOT the way to go to any of the HGVC locations, Wyndham Grand Desert, Carriage House, Polo Towers, Jockey Club, Marriott Chateau or Summer Bay.
The HGVC on Las Vegas BLVD is iffy. If it is afternoon, especially on a weekend, the tunnel and I-15 will probably be a lot quicker than Las Vegas BLVD.
BTW, a good cabby can get to any of the Strip locations without going on Las Vegas BLVD for more than a half a block. If he cruises for blocks and blocks, he's running up the meter.
