Check out the TravelZoo Cirque du Soleil local deal for details about the discounts on adult tickets. Click through to buy from the site and you'll pay $48 for seats in the lower level (regularly $80) and $40 for those in the middle level (regularly $60).
There are also $20 children's tickets for these performances:
• Thursday, Aug. 25 at 7:30 p.m.
• Friday, Aug. 26 at 3:30 p.m. & 7:30 p.m.
• Sunday, Aug. 28 at 5 p.m.
Just to warn you, TravelZoo says you'll still have to pay fees of $7.30 to $8.80 per ticket and $4.50 per order --- so your total will end up being higher than the base price. And all tickets are subject to availability, of course.
