smsm, stay more save more rates are a general public room discount.
if you book 3 nights or more, you can get the smsm discount.
ap rates can be let out in advance and sometimes they are released slowly so no way to guess when august ap rates will be known.
you could look at last years, 2015, date and rate thread and see what others paid for their august stays.
might give you an idea of what can be expected for august 2016.
in august over the past years, i have seen the room rates drop at the end of august.
(but that's not gonna help you since you plan on early august)
