I just finished ACPP in SAC. All in all I think it was a good experience, and money well spent. Lots of real world experience (x-countries) and dealing with things you might not run into at an FBO and would experience in a professional flying job. PM if you want details.

As far as advise: Get all of your written knowledge tests done before you get there, it will make for a less hurried more relaxing experience, and give you more time to really sink all that new information into your melon!
