Looks like I will be spending Turkey day weekend in JNB. I am not sure if I should thank or curse the OP. It's a great find, but this is my fourth transoceanic trip planned for the year, and I really need to stay away from this website. It is a very good time to be buying intl airfare, so I may as well exploit it for every hour of vacation time that I have.
Now, I just need to decide which pseudo safari to book. Lion Park looks interesting, but there appear to be a few whole day trips to the nature reserves as well. I arrive Friday morning and leave Sunday night, so time is not my friend (it never is).
