World Cup 2010 South Africa

I've spent a good portion of the morning researching plane fare and hostels. I need to narrow down which city to stay in. Josburg will carry a good amount of matches plus the finals, but being in SA for an entire month, well I want to go to Cape Town, Durban and Port Elizabeth to see more of SA (and the matches there). Water sports, history, and a new perspective of a different country. There are small carriers so I can go to and fro within the country, reasonably priced flights at smaller airports. Rental cars aren't bad, just need to find out about cell phone service, put my Bb Tour to use.
