Thanks Killer ---- waiting.
Btw, can you show me a pic of your setup?
Already have the other stuff that may (or may not) be needed.

Today I used the 7D, it turned out to be a wise decision because when we went in the jungle room the change in temperature was instant and the camera, lens, view finder the lot just misted up and to make things a little more difficult every now and again a fine spray like a sprinkler system would go off and this = one wet camera, it was over 30 minuets before the camera climatised, then I changed the lens and I could take my first shot 
The rest of the day was outside, spent watching bird shows and looking around the animal enclosures, this was disappointing because of fencing and meshing preventing good shots.
I posted my macro setup a while ago, but I will take some pics and post over the weekend
