Yes, since we booked early. Our rooms are reserved for Sept.
Right. So the conversion didn't really do anything because had you not made the cash reservation in the first place, you still would have been able to book it on points when you finally had enough.
The question is if you book a cash rate now (when there is point availability but you just don't have the points) and in a month from now, when you finally have the points, if they'll let you convert your cash reservation into a points reservation
even if there is no more points availability. I don't think they'd let.
