Insuffecient work experience to bridge?

I graduated from my LVN program in July of 2011 and received my license in march of 2012. Since then I have been working as a "school nurse". I recently went to a LVN to RN bridge orientation at carrington college and the director was saying that although they take all types of work experience they prefer snf experience as those students tend to do better in the program. I really love working at the school it is like a dream job but with very little pay I cannot support my family. I have been thinking that I should get a second job at a SNF but then I would have little to no time with my family. My question is does it really make such a significant difference that I should change jobs or was the director over exaggerating? I was a very strong student during clinicals in my LVN program as I have had 12+ years experience in the healthcare field as a home health aid, cna, MA, and now LVN.
