Ecstasy has had a medical emergency onboard and had to return to Cancun. This has obviously delayed the sailing for tomorrow. If you're traveling on her tomorrow you'll want to contact your T/A or Carnival for details on when to arrive at the pier.
Another good reason to have insurance. The only reason for most ships to have to re-route for medical emergency is a passenger with no insurance or ability to pay for the evac flight. They are most often handled by an outside party that requires payment before dispatch.
