I wish I had mailed things ahead of time! Sunscreen, toiletries, laundry tabs, dishwasher tabs etc. add up and take up space in the luggage. Yes, you can buy it at safeway, but who wants to spend time looking for this stuff and hoping they have the brand you want, in a unfamiliar store ( the aisles seemed random and out of order), when you can be playing at Aulani!
