Three Must-Sees: Many couples do a Moorea-Bora Bora combo, since it's an easy jet from one isle to the other. On Moorea, the Hilton's over the water bungalows (OWBs) come with marble tubs; the current here is peaceful, so swim right off your deck. Doubles from $734 (low season) and $845 (high season), with breakfast.
Don sassy shades: You're off to Bora Bora. At the Four Seasons, the OWBs have major Mount Otemanu views and palatial living rooms. Book the Kahaia spa suite, and see fish float by under the massage bed. Doubles from $835 (low season) and $945 (high season).
The swanky St. Regis boasts some of the biggest OWBs in town. (Seriously, you could get lost in there.) Doubles from $1,235 (low season) and $1,390 (high season).
Wherever you crash, do a reef shark-swim excursion. It's a rite of passage in these parts (see Couples Retreat), and the finned ones won't bite. Probably.
Don't Forget to Pack A snazzy set of pj's: You'll look nice for the hub...and the room-service crew, since you'll be ordering in. A lot.
Celeb Fans: The island group's true-blue lagoons and drool-worthy OWBs had Carrie Underwood and Mike Fisher at hello. —Jacqueline Gifford
