We visited the Cosmopolitan of Las Vegas on our latest Las Vegas trip. When we signed up for the players card we got the promotion lose $100 get it back in ecash. I lost my $100 and played with my ecash getting back about $60. My wife kept winning on her slot machine and finally lost her $100 after I had finished using up my ecash. She has a year to play her ecash so we left and will return later this year. On further comment about the underground parking garage: we loved the sensors above each parking slot. A red light means the spot is occupied, a green light means it is empty and a blue light means it is empty for handicapped cars. What a great idea!
