I am a traveler and had only 7 months of experience in my field which is dialysis, when I started with my agency. Though I do have years of experience in other areas. It will depend on the agency and their needs but definitely you will need some experience. And as for the pros and cons, it's totally up tp you, your personality and adaptability. And another thing get with a recruiter that's going to be right for you and one who will listen to you. One size does not fit all. I wish the best for you in whatever you decide to do.
