We were also on Uzima Savannah, and tho it was late June and VERY hot, we actually remarked how little smell there was, especially in relation to the # of animals we saw.
We were right in front of a watering hole and a small grouping of trees, so we had an almost constant group of giraffes, zebras, wildebeests (sp?), pea hens, etc. Well worth the price for the proximity it afforded us. The animals were visible at all times for the 9 days we were there. LOVED IT!!!!
