Thank you both. I have a monopod as well, so will probably take it (I hate lugging them around though LOL). I really like the idea of the 400 mm zoom as I know last time some of the animals were too far away. I suppose I could take the 70-200 and the 2 X extender to get the extra zoom. I have the 18-200 lens which is a great all rounder for everyday photos.
