Although Eugenie, who is paying for her own travel, has booked economy airfares and is bunking down with friends in £15-a-night beachfront hostels, her security officers are travelling business class and staying in upmarket hotels. Expert sources have calculated that the cost of their flights, expenses, accommodation and overtime will amount to around £50,000 for the six-week trip.That includes the cost of paying for two officers - at the rank of inspector or sergeant - to accompany her, both of whom claim more than £150 a day in subsistence allowances while they are abroad.
