We now have enough points to get 3 or 4 nights free at the Aria during our trip in April. I have 2 questions really.. It would appear from the availability calendars that you can book up to 5 months in advance, however the offers state they must be used within 3 months. Does this mean that by the time we stay we will be eligible for another 3 rewards as the others will have somehow expired?or maybe it won't let us book more than 3 months in advance? Also, our points are split over 2 accounts is it straight forward to use 2 different peoples points for consecutive nights in the same room?
