I think the training does cover the exam quite well for ACMP. In addition to attending the bootcamp, real-world experience will help you in passing the exam.
In addition to the VRD's that give in depth information, I would definitely study the course guides and have a thorough look at the ACMP study guide that is available on the Aruba Networks website: http://www.arubanetworks.com/support-services/training-top/certification
These study guides list the topics and show you (quite representative) the kind of knowledge that will be asked on the real test.
Don't forget to at least view the ACMA Study Guide if you intend to do the ACMP exam without doing the ACMA first. ACMA covers the first book from the bootcamp. Doing the ACMA exam first will give you a stepped approach to the ACMP certification, but that step is optional to my knowledge.
Reading VRDs may compensate for lack of real-world experience
Success in passing your exam..
