We're excitedly planning our first visit to Aulani. I'm trying to decide between a studio ocean view and one bedroom pool view. Pricing is similar, so it's a question of whether the size is worth giving up some view. Also, I'm concerned about my small children sleeping by a balcony door, while I'm back in a bedroom, asleep... especially since they are early risers. Are there any safety lock features on the balcony doors?
