This process should finally provide the quality services; (3) a focus marketing strategy should be specified to serve the specific group of tourists by offering the best service with limited resource and the cost should not be too high since it focuses only on a specific group; and (4) the retention relationship active should be certainly managed by approaching the tourist and offering them with the satisfactory services to make them feel like they are an important and valued customer.
