If you can swing it, I would say to try Cirque. It's one of those MUST SEE's and I've only heard great things about it. When I went w/ my family, my DS was 8 mos. old and slept thru it. We are taking him to a traveling Cirque in Phila in July and I think he'll enjoy it even at 2 3/4 yrs old. When I went to La Nouba and Varekai in the past I looked around and saw several youngsters between 2 and 7 just enthralled w/ the show, so your youngest might enjoy it. It does get dark in the beginning though and it has a couple of explosions and the music is a little creepy in the beginning of the show, but it lightens up quickly. The explosion didn't wake DS but it was loud. If your 5 yr old gets upset by these things, you may want to try at a later time. Otherwise give it a try.
