With that being said, you will need to do some research into exactly what type of event manager you aspire to be. There are typically three types of event managers:
1. Venue management (private venues, convention centers, arenas, stadiums, music halls, etc.)
2. Event planners (individuals within an organization or company planning events)
3. 3rd Party Organizers (companies or individuals solely dedicated to producing multiple events a year)
There are many more subgroups and variations of event managers in the industry and the exciting part is figuring out where you would like to be.
I've been in the travel industry for 30 years and done event planning. Hands on experience is critical. Contact some local hotels and function venues and ask if they take internships or if you can volunteer to work to gain experience. Travel schools are very helpful in getting industry knowledge to understand all aspects right down to room attrition. Get your foot in the door and work from the ground up. You will be amazed at how quickly that hands on experience will get you there quicker than a college degree in this field.
