Im going to make this nice and short since everyone pretty much summed up everything and said the same things.
FORGET CIRQUE DU SOLEIL AND CELINE DION
This is the MUST SEE VEGAS SHOW!
You will be in your wooden seat laughing for a good 90 minutes through.
Bring a jacket, despite the hot ass vegas weather it is polar bear freezing in the white lil tent.
oh and BTW: There are NO BAD SEATS. Its a small area in a round seating so you get a good view no matter what. So ditch the expensive tickets.
Also research online - i believe i got mine and vegas.com - i might be wrong but i entered a promo code and got the tickets for $75 flat per person including all the fees and taxes!
