BOGO stay should post as
a)$$$'s cost (pre tax) amount is all for the first paid qual night, and thus you earn points on the whole first nights pre-tax room rate
b)1x Qual night and 1xnon-qual night. 50%plus of IC's bogo incorrectly always stays post as 2qual nights.
c)if IC posts as on occasion as 2x non-qual nights, contacting Ambassador Line will resolve and you get correct 1x qual night and full points
