I have a points+cash reservation including a night which is now sold out. I now have enough points to convert to all points no cash but apparently the lack of availability will block modification of my reservation. Has anyone discovered a work-around?
Call in to reservations. If they are truly sold out that night though you might be out of luck, as they are likely oversold slightly for the usual no shows and cancelling your reservation will not result in any open availability. They might be able to work some magic around that situation but they would be the ones to talk to. Also a bunch of rules/conditions with reward stays and they might have different buckets of availability for full points, partial points, cash, etc.
