Summer interns/volunteering program - OC/SoCal

My D is in 9th grade and interested in medicine. However, not quite sure what she wants to do during this upcoming summer. Should we plan a vacation this summer or should we find EC during the summer? My D isn’t involved in sports or outside of school ECs. Any suggestions or recommendations?

Do both. Have her volunteer at a hospital or maybe shadow a doctor if you know one. Working also looks good.
