It's definitely cruise ship season. Royal Caribbean just made a major splash by launching the largest cruise ship in the world, Oasis of the Seas. That made headlines, but there have been other news stories in the industry. Last week, the huge Carnival line also had an unveiling of its own in New York City. Oscar-winning actress Marcia Gay Harden was the godmother for its new ship, the Dream.

WalletPop was invited to take a two-night ride on the ship, which is impressive but no record-breaker, as a guest of Carnival. Since the ship was packed with die-hard cruisers and travel writers eager to get their first peek at Carnival's newest vessel, it was the perfect opportunity to ask experienced cruise travelers for their favorite money-saving tips for taking a cruise.

Once you've paid your fare, your room is taken care of. So are your meals, provided you stick to the few on-board restaurants that are included in your ticket price. But after that, the costs start mounting. WalletPop's Jason Cochran, who has taken quite a few cruises himself as a travel writer, asked passengers on the sparkling new Dream for their best money-saving tips.
