Print orders for Newsstand during Soccer World Cup periods

As a magazine publisher in South Africa preparing for the Soccer World Cup in 2010, I am interested to know if anybody has experienced a Soccer World Cup in their country, and whether you can give me an indication of how your print orders changed over that period.

What we have analyzed thus far is that an estimated 300 000 visitors will arrive in South Africa over the period, that airport agents are going to be vital, that distribution of magazines - due to logistical issues could be problematic, that the on-sale period of both the June and July 2010 issues will be influenced by the Soccer World Cup.

Your insights would be appreciated.
Kind regards
