Two people referenced locking systems for their pool bags. Are you particularly worried about theft at Aulani because the resort is open to the public, or are you naturally cautious? I ask because we've never locked our stuff at any resort pool or beach (and we travel often).
Most resorts in most places are open to the public, anywhere. Most resorts will allow anyone on site to dine at restaurants, visit other guests, etc. Many will allow non-guests to stroll the grounds, they just can't use the chairs, pool, etc. So Aulani is no different in that regard.
Regardless of the resort, cruise ship, etc., I always take precautions to secure my belongings for peace of mind. Aside from having a little bit of cash and my credit cards in the bag, I usually have my iPhone and sometimes my iPad in the bag as well so I can read while at the pool. I would not want to leave that unattended at my chair to go in the pool or the ocean, restroom, etc. So while theft isn't necessarily rampant at Aulani, I just think it would be irresponsible anywhere to leave personal items of value unsecured.
But, if you don't have any electronics or cash in your bag, then I wouldn't worry about it. We'd often leave our flip flops and cover ups at the entrance to the lazy river and no one bothered it and we weren't worried about it either.
I haven't seen a rice cooker mentioned in any other posts. I assume you had a one- or two-bedroom villa. We will have a studio. Is a rice cooker something I can request from Mousekeeping? I'd love to have one in the studio.
We had a studio and there was a rice cooker in the cabinet. We did not use it. I think rice cookers are standard in all DVC units due to the amount of guests from Japan/Asia.
