To the best of my understanding, you don't actually need to use the code any more; if you book a stay of the appropriate number of nights with no code at all, you get the SMSM rates. And the same rates are used as the base rates on Orbitz/Cheaptickets.

yes, i noticed that this year when i was checking for another stay onsite.
(already booked the october stay last november.)
putting in for a 3 nights or more stay, brought up the smsm rates when you got to the section of selecting room type.
nice.
