We are arriving on may 6 too! This will be our 7th trip here. Not sure what travel docs you are referring to. You could print out your room confirmation I guess. If you booked a shuttle separately or a rental car you should probably have those receipts. There is no magical express in Hawaii so there are no luggage tags. And if you made reservsti9ms for excursions, restaurants or the luau, I always make sure the confirmations are on my phone.
