2. O by Cirque du Soleil
O by Cirque du Soleil is one of the most famous shows in Vegas. It involves a mixture of dance, acrobatics, and swimming performances from a huge water pool. It is a magical experience watching all the acrobats, swimmers, and divers in their element, creating art in perfect coordination from their graceful movements and well-choreographed performance. This is one of the few shows I'll recommend to everybody- old, young, you name it!
