Yes should be fine although you are already past the 7 month window for that week. I just booked two weeks ago for February 19 to 27 and everything was open except hotel rooms. Had I wanted a hotel room it was available the day before my window opened so I could have even gotten that by walking the reservation. However I would guess Aulani bookings might be down so I wouldn’t count on hotel rooms at 7 months normally even with walking
