You can always search for price in points without event being logged in. If a standard room reward rate is offered, this is eligible for 5-4-4 redemption - otherwise, if only premium room reward rates are offered, these will be due for every night during your desired stay period. By way of reminder, when you search for one specific hotel and select that your dates are flexible, you will see the entire availability and price calendar (this does not work when you search by destination).
