Nearly two-hundred children with serious illnesses and disabilities have just returned from the trip of a lifetime.
They were taken to Orlando, Florida, by the Dreamflight charity. All the children are aged between 8 and 14, and they went without their parents.
They were cared for by a team of doctors, nurses and other volunteers. The charity's founder, Patricia Pearce MBE, said: "All the adults are so, so dedicated. They're all volunteers and to see that dedication and love going to those children - it's heart-wrenching."
The ten-day trip involved visits to all the main attractions, including the Disney parks, SeaWorld and Universal Studios.
Ria Thomas, 12,told us: "I'm really enjoying it and glad to be here because, this time last year, I was in hospital and now I'm in Florida on holiday, so it's great!"
