I did a business administration degree at Bristol University and then worked for a credit card company for eight years. During this time, I was assistant marketing manager. I gained a lot of useful experience doing this job, but in 1997,1 decided that I needed a change. I moved to Thomson Holidays where I have worked as a manager ever since. My main job is to think up new and interesting ideas for holidays.
When I'm working from my office in the UK, I arrive at 9 a.m. First I answer my emails, then plan the day. My role is to investigate new projects for Thomson Holidays in our Mediterranean resorts. I am responsible for coming up with ideas, developing them and evaluating their success.
We have lots of meetings in the office which involve the marketing department, holiday reps and people that we bring in from outside such as entertainment organizers. The aim is to develop an exciting idea into a realistic and workable project.
Once a month I spend a few days overseas checking possible resorts, meeting with reps to develop their roles and working out how events should be sold to the customer. I work with resort supervisors, use their local knowledge of bars and clubs for venues, talk through new ideas and find out how existing ones are working. I also meet holidaymakers.
I have to be very open-minded because ideas come from anywhere. I love my job because I get to travel and I am working on a project that everyone loves.
