Career advice needed!!

Ive been a nurse 3 years and cant seem to find a floor/specialty that suits me. Recently the opportunity has come up to get out of floor nursing all together. Id be working in an office using my RN degree to review medical files. No weekends, holidays, overnights....sounds like a dream!
Im just worried that if I take this, I'll never be able to get back into floor nursing if I choose to. Does anyone know of a situation like this where someone left floor nursing for an RN office job and had a hard getting hired back into a hospital?
