Just returned from Aulani and rented a Cabana. It is $250 per day--complete with a fridge and TV (great for those poolside days watching football). Disney Cast Members and DVC Members get 10% off.
The Key is WHICH Cabana you book. The best one is Cabana #1 which sits on a corner over looking the ocean (perfect sunset views) and the pool, #4 is the one we rented which is on the other corner (visualize four cabanas in a row, #1 and #4 are on the corners and 2 and 3 in the middle). The corners are nice so you can gather other lounge chairs around if you have a larger group.
Beware of Cabanas #5 and #6, they are by the Mennehune Trail pool. Now you might think "that's great because it's where the kids will swim" but they sit at the base of water slides -- so you will get no quiet moments at all and you can't see the ocean; plus the 9 kids we were with didnt spend much time at that pool.
If you are paying the money book Cabana #1 and #4. Just call the Aulani Concierge to book them.
PS -- Aulani is so absolutely, positively the best family vacation we have taken and we have stayed at over 10+ Disney Resorts as well as Ritz, Waldorfs--as one Cast Member told me "Aulani will change your life" and it will.
