Did someone say they were throwing a party? Because, if they did, then as an event coordinator, you're all over it. Every aspect of the party or event is under your responsibility. You get to research and find the perfect venue. But you also have to stick to the client's budget, which can sometimes put a damper on the planning aspect.
Being an event coordinator is much more than just throwing a party, though. There's some stress you'll need to be prepared for, as you have a budget to stick to and don't forget the date of the event. The job also comes with a lot of research. Some of that will be able to be done through the internet, but you will have to do some in-person research like visiting a venue. So don't expect to just hang around the office every day.
This goes without saying, but an important aspect of being an event coordintor is being organized. Organized, organized, organized. It's almost impossible to be an event coordinator while simultaneously being unorganized. Those are just two things that do not get along.
