Well,I can tell you what is my least favorite hall carpet in a casino, and that is in the Flamingo.HOLY ACID FLASHBACK DUDE! Stood in a hallway upstairs while waiting for some friends to check in and I looked down the hallway which seemed to go on for days and....well,if you are a Seinfeld fan,do you remember the episode where Kramer kept going into epileptic seizures whenever he heard Mary Hart's(sp) voice? Well...when I saw that carpeting,I started hearing old Doors and Hendrix music in my head,started seeing bright lights, and thought I was going to lose it.
C'mon though...surely(Pam perhaps?)...someone has carpet samples out there from every casino. Heck,I even considered it one day when I happened to pass by a Treasure Island dumpster one day and saw some carpeting in there that had been tossed out.
