On the Beach chief marketing officer Alistair Daly is leaving after 10 years with the fast-growing group.
He will leave at the end of this month to pursue a non-executive career.
His responsibilities will be taken on by Alan Harding, who joined On the Beach in 2014 as performance marketing director and who has been promoted to marketing director.
Founder and chief executive Simon Cooper said: "Alistair has been instrumental in the significant growth and success of On the Beach over the last 10 years and it has been an absolute pleasure to work with him. I would like to personally thank Alistair for his exceptional contribution to On the Beach and I wish him every success in the future."
