When we received the intitial materials about the trip, there was a warning that our itinerary was subject to change because of civil unrest or political events. We just considered that standard boiler plate disclaimers.
When the final materials arrived, we were informed that our original hotel on Easter Island was being occupied by the indigenous people in a protest against the Chilean government. No big deal as we will just stay at a different hotel.
But the civil unrest in Egypt is a different matter. We are scheduled for two stops in Eygpt and one is in Cairo. Our guess is that there is going to be no resolution of the current problems by the time we are scheduled to arrive there. Our further guess is that we will not go to Egypt and will be rerouted to Jordan.
