i've had my preferred ap since 2002 and booked many stays with it and they were rates you couldn't beat.
then changes started to happen.
3rd party vendors were getting great discount deals.
book with them and you didn't need the ap at the darkside for a reasonable room rate.
now smsm came out to include the general public.
i'm guessing that the last 3-4 years, i have booked with that rate.
my long stays are about 2 weeks.
with using the smsm rate, i'm getting the best rate possible.
discounts using smsm begin at 3 night stays.
higher discount as you add more nights to the stay.
7 nights or more is the greatest discount, it beats orbitz and ap for the time period i book.
booking dates can have different discounts.
always check orbitz, ap, smsm, aaa, mil, etc to see which offers the best for you.
its all flexible based on your dates and type of room, hotel, you want.
you can go back and search on the forum for Date/Rate thread.
there is a current one for 2016 and threads for 2015 and 2014.
it can give you an idea of hotel rates with the discounts of those that posted.
hth.
