Flights $718 + hotel $1,862 + resort fee $207, taxes in · a checked bag each adds about $240

The catch: Both flights make two stops, the flight out takes 36h 21m with an overnight connection, and a checked bag is about $240 for two.
Worth it if you'll trade a long travel day for a warm island week; skip it if you want a short, easy flight.
