Sorry to resurrect this for a related query. Pretty sure this has been asked before and should be something I'd know, but for the life of me can't remember:

How is a single stay comprising of back-to-back reservations, one entirely on points and the other entirely on cash, treated for the purpose of points accrual? Is the entire stay of both reservations treated as equivalent to a regular Cash and Points stay, i.e. the cash component does not accrue points? Would seem logically consistent with the treatment of back-to-back reservations as a single stay.
