I'm taking my mom to see a Cher concert near the end of May.

I know my mom also likes Cirque du Soleil but even the cheap seats are expensive and considering how much I paid for the Cher tickets (I got the good seats) I think she'll object to me spending so much on them. The Cris Angel show with the Cirque du Soleil people is cheaper but with the flashing lights and smoke machines it'll be one big migraine and asthma attack for me.
Does anyone know of anything they'd recommend? We'll be flying there on a Friday and coming back Sunday morning.
