Sienna-Grace Lindfield, from Basildon, is currently being treated for Neurofibromatosis Type 1 at King’s College Hospital, Great Ormond Street Hospital and Basildon Hospital.
The Disneyland Paris specialist is supporting The MCA Trust, a volunteer-run Essex-based charity which grants children with brain-related cancers a "special wish" or donates a piece of equipment to help make their lives easier.
The MCA Trust held their charity Golf World Cup event at Langdon Hills Golf Course this week which saw 18 teams, including Instant Breaks as well as Vertical Systems, take part by playing 18 holes and sponsoring the event, which has so far raised more than £6,500.
Instant Breaks operations manager Ashley Davies said: "I have spoken to the Lindfield family, and this is a dream come true for Sienna and her sisters who until now could only dream of meeting princesses.
"This break will give them time away from the day-to-day toll of hospital visits and treatment. Instant Breaks feels very honoured to be given this opportunity to arrange this once-in-a-lifetime trip."
