I got a fairly large (albeit non-offensive, galaxy forearm tattoo) during nursing school, which was definitely against my school's policy but I'm not going to let a school dictate my personal choices. I've never had an issue on any unit, though I do live in a fairly large metro city. However, if an employer is not going to hire me based on my tattoos versus my qualifications I'd rather forgo that unit. It's your life, it's your body. Not everyone is going to understand but they don't have to. With that said, my final preceptor placement has been on a specialized high acuity critical care unit so I guess the tattoos didn't really matter :) Good luck and be yourself!
