Dan Hanrahan, president and CEO at Celebrity, said in a recent interview that he is frustrated that travel sellers are not as proactive with their clients as they could be. "I find it frustrating when agents don't follow up with clients who just got off a cruise," Hanrahan said. "Those clients are ripe for another cruise. If an agent isn't following up with a client right after they've returned from a cruise, that agent is missing a huge opportunity." Because of this, Hanrahan said it only makes sense that Celebrity would engage in direct marketing.
