For our first-ever visit to Africa this August, we fly to Jo'burg, then take our rental car straight to Kruger for 4 full days (mostly self-guided touring, but we hope to arrange a morning and a night guided tour on arrival). Our budget and timeline limit us to a total of 4 days for our 2 other major game parks, Hluhluwe-iMfolozi and iSimangaliso Wetlands. Lonely Planet says that a three-day, two night walking trip (Short Wilderness Trail or Bushveld Trail) is a "once-in-a-lifetime experience", but that would leaves us only one day for St. Lucia, the Eastern Shore, etc. Or should we switch our priorities and spend 2-3 days exploring the St. Lucia area's ecological diversity, with a day's self-guided drive through H-I Park thrown in? Any and I mean any advice would be welcome!
