In a Fix

Good day All. i am a 26 year old Female with a degree in Corporate Communication, which i obtained in 2004, so its been three years of waiting and i reckon my degree has gone "stale" now. I would love to pick the brains of those people that have been lucky enough to land a job in PR/Marketing. I would like to Further my Studies/"Upgrade", so My Question is: Being in the industry for as long as you have been, which would course would you say is better coupled with My Degree? and why?

1. Marketing and Sales Diploma
2. Conference, exhibitions and events Management

Both are short couses, but if you have anything better to reccommend feel free to advise a sister.
