Do you think this will be a problem?

I just got my RN license and I am going to start work in a few weeks. I have a scholarship through our local hospital, so I am going to work there; however, I have to interview still to decide what unit I'm going to work in. I am getting nervous because I have a vacation booked for the first week of September. When I booked the vacation I thought I would be starting work in May when I graduated, but the hospital decided not to let us start until we had passed the NCLEX. So I thought I would work all summer THEN take the vacation. Money is not an issue and I don't mind unpaid leave but I am worried they are going to give me a hard time about taking 9 days off so soon. WDYT? My dh thinks it's not abnormal to start a job with a vacation planned (esp in the summer) but he's in a different line of work, so I just don't know and I'm starting to get stressed about going to the interview and having to tell them this. I really can't get out of it (nor do I want to) as I've already paid for the airfare, and it's kind of a thank you to my family for being supportive while I was in nursing school and kind of neglecting them.

Thanks for your opinions!
