First-time poster, long-time lurker. These promotions definitely work in concert -- a stay from last week just posted at 820 base points & 11,410(!) bonus points for a total of 12,230.
After my 50% Platinum bonus I can't quite piece together which promos make up the other 11K -- don't yet have the 7 stays needed for the 10K in 5960 -- but that's OK as long as the points keep coming....
