Pre-covid, ocean view rooms, all sizes, were typically open at Aulani at 7 months out for any time in March and April, including the Easter weeks.
Possible problem with 2022 is potential of many members having large amounts of extra banked points accumulated during the lengthy covid closure at Aulani, which could raise the usual demand for the time you want even though it will not be an Easter week in 2022. Thus, whether you will succeed is unclear but I am guessing chances are still decent based on prior history.
