Sept 23 - Vanessa Williams accompanied by the Vegas Philharmonic  
I didn't check to see what the ticket prices are.  
Now for the bad things about Monte Lago  
They only let Lake Las Vegas Residents and Hotel guest rent their boats/paddle boats.   
The rental guy said he had to turn down over $2,000 worth of business there yesterday.   
According to him, its not the Marketting Exec, 
its the owner (a Railroad Tycoon) that made that decision.   
Also, the home buyers out there have to sign a 'must sell' clause with the owner 
in order to purchase a house there.   
In other words, they can be kicked out of their home. Weird.
