My husband and I are planning a cruise to the Panama canal. Has anyone taken the ocean to ocean train shore excursion in Panama? Is it worth it? Or should we just stay on the ship and experience going back through the locks again? Our ship goes into Gatun Lake, floats around a few hours, and then turns around and goes back out of the locks to the Caribbean. Are there any other must see excursions in Panama or Costa Rica?

Thanks, Minna
