TONY HETHERINGTON: 'I cancelled my Marco Polo cruise because I wasn't told I'd need a doctor's certificate for my Parkinson's - now it has refused a refund'

The booking was made by phone with travel agent World Travel Lounge and she paid a £200 deposit. When the paperwork arrived a few days later it became clear I needed a doctor’s certificate saying I was fit to travel, as I have Parkinson’s Disease.
