The Rezidor Hotel Group area vice president for the Middle East, Marko Hytonen, will leave his post at the end of January.
In a statement, Hytonen commented: "My time with Rezidor has seen me fortunate enough to work all over the world; it’s been a time full of adventure, challenges, wonderful people and memories.
"I have been in the Middle East for the last three years, during this time I have worked with some truly incredible people both within and outside of Rezidor. I would like to take this opportunity to thank each and everyone for their support and cooperation.
"Even though it’s sad to say 'Goodbye', I am looking forward to a new and exciting challenge, but first I will spend some time with my family."
