アラモアナショッピングセンターには、アロハシャツ等レンタルショップは無いと思います。 ウェディングでしょうか。 ワイキキショッピングプラザ3階にレンタルショップがあるようですのでそちらはいかがでしょう。 アロハシャツもムウムウも安いので現地で購入しても良いとは思います。 買う際はメイド・イン・ハワイの品をオススメします。

pretty sure they don't but you can leave your luggage with the porters who have the luggage in an area only accessible by them so it would be safe.

Se non ricordo male non ci sono supermercati ma solo negozi e boutique e qualche ristorante Al livello più basso, quello dei parcheggi, ci sono poi i ristoranti quelli più economici

Yes

Target is open to 11pm. Fairly sure the others close at 9pm

Unfortunately I haven't compared prices. I think it depends on what your looking for, they do have a Nordstrom there that has sales for high end stuff but limited selections. The other readers are right about going to the outlet malls far cheaper but don't have the really high end stores like Chanel or Gucci etc. Another choice is to go to the DFS duty free malls. you'll save a little there on high end stuff.

We did not find a free shuttle but we took a low cost shuttle that left from near our hotel
