Accepted to CRNA program - Do I go back to ICU?

I became a nurse in 2012 with the intention of becoming a CRNA. I worked in Med/Surg, a Medical ICU Stepdown and CVICU. While in CVICU, I intended to apply for a CRNA program after one year. I eventually applied to one CRNA program and thought that if I was accepted then I'd go and if not, then it was not meant to be. While waiting for the decision, I began having second thoughts about the stress and pressure of school without any income.

After 6 months and no response, I started to look at other graduate programs in nursing. I eventually decided to pursue Informatics and got a position in Health Informatics. While in my new role, I was called for an interview to the CRNA program. I did not want to pass up the opportunity to potentially become a CRNA and went into the interview with the intention of attending if I was accepted as I knew I would regret passing up the opportunity.

Fortunately, I was accepted in the the program. My question is, do I go back into the ICU to help maintain my clinical skills and increase my critical thinking of critically ill patients or just pick up a per diem in the ICU for the same purpose? I have my CCRN and two years of CVICU experience. I don't want to enter the program next year looking incompetent during clinical from the time away from bedside. I understand going back to the ICU would be ideal but I do not want to pick up a position in ICU and leave within a year. Please help!
