When you are scheduleing your activities for the day at this resort; do the boat tour up to the falls in the morning.  It will be cool enough for the crocs and hippos to be out of the water.  You will see a lot more animals.  We saw hundreds of crocs and hippos as well as dozens of wild elephants and water buffalo. Take your safari ride into the park lands in teh evening as the lions will be out later in the evening for their hunt. We saw every animal there was to see in one day save one big cat.  We did get to see a whole pride of lions including cubs.  We saw so many giraffe that we actually seemed to get bored with seeing them!
