Degree Vs Masters?

I have nearly completed a BSc degree in Business Information Systems and I am unsure of what to do next?
Does have a masters under your belt really make all the difference or do people merely choose to do a masters in order to "buy time"..

As I am interested in the whole web content side of computers, I discovered the MSc in Interactive Media is a course I would be very interested in... only a year long, if it allowed me to pursue the career I want surely its worth the time.  However, If I can obtain these jobs with a BIS degree anyway..am i just wasting time considering the masters?

Huntington Beach - Surf City

Heading to Huntington Beach for the summer with the aim of working in some low pressure industry, preferably outside so I can just enjoy the summer.  Does this type of job even exist?

Originally I thought perhaps I should apply for internships related to my computer course, i'd certainly make more money.. but this is the only j1 i'll go on so I decided to just enjoy myself.

When I get back the question is.. do i do a masters or work?
