We went to The Mirage casino, got some popcorn and diet coke, and went to see Beattles' LOVE from Cirque de Soliel.

It was amazing. It gave me goose bumps. We both really like the Beattle's music, so we knew we'd enjoy that part, but the rest of it was beyond our imagination. They do amazing things with costuming and acrobatics, not to mention the imaginitive coreography. The tickets were very expensive, but we think we got our money's worth and we'd definitely recommend it to anyone making a trip to Vegas.
