Pirate show at treasure island is long gone. Leased the real estate for development.
Honeslty I would avoid Circus Circus like its the plague. Place is so old and just blah.
M&M factory is a must, MGM lions, NY NY is incredible, Excalibur is a joy to stroll thru, Luxor is wicked amazing to wonder around, go to the top of the stratosphere at night, Hoover dam, bellagio fountain show, the Linq ride might be open now.
Get ready to talk to him about porn. Sun goes down and you're gonna be given all the free prostitute magazines you can stomach and I'm not joking either. Used to have incredible arcades in Treasure Island. Caesars two marble statue shows are neat and free. See them in the forum shops. Wonder around the canals of the Venetian.
I stayed at the Luxor last time, I can attest it is pretty great!
