I just booked a stay at a Cat 7 hotel in Hawaii with Rewards points. This is my first experience with use of Rewards points. While the system accepted my reservation, as I looked over the confirmation I noticed the reservation fell right in the middle of the holiday blackout dates. Should I be worried that we'll show up at the hotel and be refused our reservation? Or is it possible that occupancy is so low that some properties are ignoring the posted blackout dates?
