Trying to Book for January... do I need to wait until I hit 90 days out, or do I just have to call and reserve it within 90 days of purchasing the reward?
If you're talking about rooms and shows, you just need to book them within 90 days of purchasing the rewards. So, if they're available for your dates, you can go ahead and get them, but once they are booked you can't cancel and get them refunded. For rewards that have to be redeemed in Vegas, you should wait until 90 days out to get them, and ideally give a few days cushion just in case you don't use them to give you time to get a refund. The rewards expire within 90 days of purchase and once they expire, you can't a refund.
