Hi, we’ve got around 50,000 points expiring this month, we typically used Hilton lots but since covid, much less hence them expiring. We don’t want to lose them, but we don’t think we can stay before they expire.

can I book a room for next summer adding the extra £50 cash to the booking? Will that keep them active? Can I still cancel the room as usual if needed?

or can I keep the points active by buying more? 1000 points for example just to keep it open?

thanks muchly!
