Hello folks

I have an award night booked, and for that date the availability of award nights ran out. I'd like to change it from points-only to a cash+points reservation (in order for the stay to count as a cash+points stay for purposes of one of my accelerate promo tasks).

How does cancelation of award nights work in this respect - does the availability instantly get released back so that I can rebook it? I'm willing to take the chance that nobody else grabs that room in those few seconds...
