A few months left of a gap year

I am on a working gap year; and so far I've had 5 diffrent jobs. The first job was paid but the other 4 were internships and voluntary. So far the jobs I've had are 2 in accounting, 2 in marketing and 1 in sales. And as of May 5th I'll be unemployed. I'm going to University in September to study business management so I have a few months left and I was wondering what I should do until then. I have a few grand to play with as well. I don't mind working and I don't mind traveling. Its genuinely a difficult decision. Any suggestions what I should do?
