TEN excited children have just arrived back in town after a visit to Tokyo Disneyland. The children, who are cancer patients from five hospitals, got the opportunity to fulfil every child's dream thanks to the generosity of two businessmen, who insisted on remaining anonymous. The businessmen footed the $200,000 bill for the five-day trip for the children, an accompanying adult for each child and two nurses. Organised by the Children's Cancer Fund, the trip was, said executive director Juliana Tam, one of the most exciting things to happen to these unfortunate children. ''It was such a thrill to see the joy in these children's faces. Most were travelling on a plane for the first time in their lives,'' Juliana said. The children, none of whose families would have had the financial resources to pay for the fabulous trip, were the fortunate ones. But there are many more the Children's Cancer Fund would like to treat in a similar way if it had the funds. So anyone who would like to offer help can contact Juliana on 815 2525.
