We are due to board Silver Moon in Muscat on 16 January. We know that the previous cruise will depart from Jordan on 6 January, but will it, in fact, be able to complete its journey to Muscat as scheduled? It entails making the passage via the dangerous Bab al-Mandab Strait. Has any cruise ship actually undertaken this risky journey since the rebels began launching their attacks? We certainly do not envy Silversea having to face this decision, but the clock is ticking. Passengers will require clear information.....
