I took a boot camp class that was 5 Saturdays in a row. This was good for me because it gave me a chance to study the materials between classes. I passed the PMP on the first try after this. The only negative thing was the people in the class who had no previous project management education or experience. These people came to the class expecting to learn project management and then take the PMP in order to get a better paying job. These people had a very hard time in class and as far as I know the few you actually took the test failed. I think the boot camps are great for those who have prior experience and some project management formal training/education to prepare for the PMP test. I do not think the boot camps are good for those trying to break into project management for the first time.
