One wing of the resort is hotel rooms (which includes some 1BR and 2BR suites), the other wing is DVC studios, 1BRs, 2BRs and 3BRs. The hotel room wing is available only for cash through Disney and not on points using DVC except for 8 standard view rooms -- not ocean view but mainly parking lot and garage view rooms. Thus, unless you want to do a cash reservation through Disney, you cannot get an ocean view hotel room. The standard view hotel rooms for DVC are very nice and larger than the studios but, like with other DVC rooms, you do not get daily cleaning service unless you pay extra for it (and it is not cheap). Moreover, you are not likely to even get a DVC hotel room on points unless youi reserve 11 months out because those and any standard view DVC rooms at Aulani can go quickly almost any time of year once the 11 month window opens.
As to the DVC studios, there is a booking category for ocean view but as many have reported there is no guarantee of full ocean view but just of partial ocean view with the result that some ocean view rooms have better views than others and you cannot assure getting the better ones.
For studios, ocean view is usually the last to fill. However, much of June (after the first 5 or 6 days) is one of Aulani's high DVC demand times of the year and even ocean view is hit or miss and much that is open can disappear quickly once the the 7 month window opens.
