Nothing too crazy except the prices. Five dollars would be a fair price for this event, clearly not the $13 weekend price. Fairly short trail of lights with some animals, some trees and a few things lit up in the water. The LED monkey was my favorite as was the blue tree. We arrived about 15 minutes before closing which was actually good because the whole zoo parking lot was jammed with everyone leaving. The lights are much better with no families of kids screaming right next to you or teens doing their zoo light thing. I gather that everyone must go see Zoo lights once in the lives if they live in Phoenix for awhile, so its off the checklist. It can be romantic also after all the people clear out and the lights glow softly on the water. Oh and there are actually one set of live animals available to see and that would be the flamingo's, which are at the beginning of the walk behind some secret bushes.
