Tunisia's airports serve both the capital and a series of coastal resort zones, and the transfer logic is different for each. Arrivals at Tunis-Carthage headed for a medina riad are a short, urban transfer. Arrivals at Enfidha or Monastir headed for a Sahel resort or a desert camp are longer regional journeys where a pre-booked vehicle with clear pickup details saves time and removes the negotiation that otherwise happens outside the terminal. In a country where taxi pricing outside airports can be variable, booking in advance with a fixed rate removes one of the more predictable irritants of a first day.
