That's my thinking too. In fact, South Point would be a great "plan B", if things go sideways, with the Rio. While SP is not on the Strip, it is only about 10 minutes south of Mandalay Bay, on Las Vegas Blvd.
I'm sure Mark Griffin has spoken with the ppl at SP. I have no idea if the talks ended with a "definite maybe" or a "slim to none".

Love the SP- You could really get bargains there when it first opened. If you have a car, everything you need is within 5 miles east of there as well.
