Nursing to PA advice

Hey everyone. I am an RN working in the ER. I am contemplating pursuing PA. I believe the education is superior to NP (experience dependent) and like the idea of not being stuck in one speciality and being able to laterally move as my interests change. Has anyone done this and have advice? I guess I am curious to know if my experience will be helpful and also is it a realistic goal to think I could get in to emergency medicine out of PA school? Currently 2.5 years experience and would plan to work per diem during school if it is possible. Thank you!
