“From the moment we pick everyone up, the trip is simply wonderful. There are surprises, treats and new magical experiences every step of the way.”
Dr Johansen said many of the families, including some from London, have not been on holiday before because of their children’s health but the medical support makes it possible.
“That for me is fabulous,” she added.
Mr Davis says that 90% of the parents and carers do not tell their children about the trip until the night before.
Early on Friday morning as the black cabs left Canary Wharf, the Royal British Legion band played music as they began their journey.
After taking the ferry from Dover to Calais they were driven to the theme park in Marne-la-Vallée, about 20 miles (32km) from Paris.
The children spent their day at the Disneyland theme park on Saturday.
The special event ends with a formal dinner and disco and they will head back on Sunday.
