Cirque du Soleil has mounted no less than seven ongoing shows in Las Vegas, each at a different casino, as of 2010. How? While Mystere, the first, is basically a touring show taking advantage of a fixed abode, each of the other shows puts a twist on their style:
"O" uses a giant pool for its stage, so all the acts incorporate water in some way (including diving and synchronized swimming).
Zumanity is adults-only.
KA has a linear plotline told through its acts, plus two moving stages to create its settings.
LOVE is themed around the music of The Beatles; there's more dance than usual, too.
Believe is a magic show where the troupe plays a supporting role to Criss Angel.
Viva Elvis is built around Elvis Presley's life and music, but more straightforward in its approach than LOVE.
