Obviously you are not aware of the 'Kruger' issue. Oversee tourists are not problematic at all when it comes to alcohol consumption in the park. They have never been. People who can afford to sleep over a few nights, are pretty well behaved too. That leaves the 'poor' day visitors who just want to have fun for a few hours. There is no tour guide to check on them. Their particulars are not known. After they pay a fairly discounted entry fee, they think they own the place. I am all in support of this measure.
