Organisers booking delegates into hotels overseas might want to enquire reference the hotel’s policy for guests who become ill, or are injured during their stay.

Some hotels are being bribed to deliver them to expensive private clinics where the guest’s travel insurance cover may not be valid, leaving them to foot the bill.

Guests, or their organisers, should always contact their insurers on the emergency hotline for any kind of medical emergency or need for treatment, to allow them to find a state-run facility in preference to a private clinic that may have bribed the hotel.
