Split stay vs Booking an Aulani night for pool access

[Runnsally]

Hello, all. Will be staying at the Four Seasons Ko Olina, but would like access to the Aulani pools for a few days. Any issue with booking a one night stay, including all 4 of us on the reservation and getting two days of Aulani pool time? Alternatively, may make more sense to tack on an Aulani day or two at the end of the stay to get a similar experience - has anyone done either of these things? Thanks much.
