I was there in May and one of the highlights of my stay was the Cirque de Soleil show in Treasure Island. We bought tickets on the morning of the show at the half price booths for Mystique and is was AMAZING...the BEST show Ive ever seen. Really good value also. I've been to other C de S shows in Eurpoe, staged in the Big Top but the fact that the Treasure Island one is performed on a purpose built stage I think made the show even better. Would have loved to see 'O' in the Bellagio but i think its sold out for months and months. Hubby was open mouthed through most of it and he isnt one to be easily impressed, not really a show person at all. What these guys and girls can do is unbelievable.
