capt_noonie, have you been to Vegas before? If not, then I don't recommend seeing a show for $100/each when you only have 1 night there.
A lot of the casinos on the strip have their own 'free' shows and you can walk the strip for many hours and see them all for free. Mirage has an erupting volcano that is fire, lights, water .. very cool. Treasure Island has the best show every 15 mins I believe or 1/2 hour, its a mini show, with 2 ships and they have a fight over your head with fire, water, explosives, etc.... very very cool! Excalibur has a dragon/wizard type show, kind of less excitement than those other 2 but still neat. Bellagio has the dancing fountains that are GREAT. Rio has an indoor ceiling show with floats and they throw mardi gras beads down, and a stage comes out of the floor and has an Elvis on stilts and barbie girls dancing and this just randomly happens in the casino, all for free!
Check out this link, there is enough FREE stuff to keep you busy for a week!!!

This is a better way to SEE Vegas if you've never been in my opinion! The shows ARE great, no doubt. I seriously did not see 1 show until my 3rd time to Vegas because I spent so much time seeing all these things for free that are really cool!
