Honestly, I didn't expect to like this show so dang much, but I absolutely do. It's one of the more affordable Cirque shows, AND it's really great if you are a visual person.
This is one of the most acrobatic shows I've seen on the Strip. Tons and tons of amazing feats in large, stunning quantities will leave you amazed. Visuals are huge for this show. Glowing rainbow colors are present in abundance for every piece, and costumes are wild and fun.
I was super impressed by the visuals and acrobatics of Mystere, but do make sure you get enough sleep before you go. The music is that semi-soothing, ommmmm type of stuff, you know? I was getting sleepy by the end, no matter how cool this was. So relaxing that I skipped the club and went to bed right after.
Check for discount tickets either on Cirque's website or day-of at Tix4Tonight. These go pretty fast from what I understand. Parking is Fuh-ree at Treasure Island, and you can squeeze by the Krispy Kreme Happy Hour as you walk back to the parking lot.
