She laughed and chatted with carers as they carved pumpkin lanterns and learned circus skills during a respite day at the Somerset resort.
The Princess Royal, President of the Carers Trust, who was cheered by families enjoying half-term at the resort, unveiled a plaque to recognise the support Butlins gives the charity.
Butlins team has raised almost £250,000 over the past five years and offered work experience to carers who have had to look after a sick or disabled family member or friend.
About 75 carers and their families were invited yesterday to enjoy Butlins’ fun activities including circus skills, arts and crafts, face-painting and story-telling.
Resort director Julian Highfield said: "This very special visit by HRH, The Princess Royal, means a huge amount to the team here.
"Butlins has enjoyed working with the Carers Trust and is proud to have raised almost a quarter of a million pounds. We have also been fortunate to be able to offer some carers the opportunity to join us on work experience in a number of departments here on resort."
Carers Trust Ambassador Carole Cochrane said: "The Princess Royal is a very active President and having her support raises awareness for a charity supporting the six million carers in the UK.
"The carers invited to Butlins today have had a fantastic time, meeting the Princess, enjoying lunch and the resort’s facilities, a lovely day out which is something they don’t get very often."
Tutsi Muchanyuka, 29, from Hackney, London – who personally thanked the Princess for helping carers – looked after his mother for 11 years up until her death last year. He was supported by the Trust and has now joined the team at Butlins in Bognor Regis after work experience.
He said: "Today has been so exciting for all the carers here. The Trust gave me support in so many areas. It gave me my self-confidence back and the boost I needed to move my life forward."
