Here's what we did after our 8 AM disembarkation in Tahiti about a year ago. Booked a room for that evening with early arrival at the Sofitel. Had an amazing day. Much better than the so-called day room, which was a banquet hall crowded with cranky travelers killing time until their flight home around midnight. Suggest you book through Starwood and ask for the "Retirement Rate." We paid $244.53 for a Garden Room last year. Pre-booked a 7 PM reservation at their up-scale Le Carre restaurant.
