I was researching booking Las Alcobas Napa over the weekend, before the change, and found some dates but didn't commit (my mistake, I know). Now I'm getting this error: We’re sorry. This property is not taking redemption bookings at this time. You can either book a cash reservation or search for another property.
Very frustrating. If they're going to make changes effective in the future, you should be able to actually book them before the effective date...
