ICU or GI Lab dilemma

I am a new grad (May 2010) and have been working in CVICU on my own since October. I currently work nights, with a family (2 kids and hubby) is has been challenging to work night and feel like I can't participate in life when I an not working. I moved 2000 miles for a RN job because my home state has limited jobs for new graduates. My long term goal is to go back home and work. I have applied for a position in the GI Lab at the same hospital, and should interview next week.

My question is should I stick out the next 18 months in the ICU and return home with my experience or go for the day job in GI Lab. I am afraid that if I took a position like GI lab that I would be limiting my options when I return home. I just don't want to limit my experience so much that I can only work in a GI Lab type environment and then not be able to find a job later.

Thoughts???
