I'm currently working on my A license at Mile-Hi. The AFF instructors were great and the coaches have been fantastic. The canopy course is especially helpful. The experienced jumpers I've met will take time to help or answer questions. It gets VERY busy on the weekends, so I recommend getting there as soon as they open if you want to get in more than one jump. During peak hours, it can be tough to get a rental rig. I would guess owning your own chute makes more jumps possible.
