The 2008 rates are not in the system yet. The rooms mgr at PBH told me the rooms at least should be in the system sometime this month.
With APH, you also need to keep an eye out. Many times the APH rates go down as your trip nears. Also, log into the APH holders website. It will tell you through when APH rates are available. I believe the good rates are only through October right now.
Book at rack rate and then keep a watch out for the APH rates.
