I'm not sure I'm be brave enough to travel around for fear of missing my flight.
We barely made our 12:35 pm flight, there was a 45 minute wait to get off the ship, and a 90 minute wait to clear security at the airport. We literally walked from security right onto the plane.
I'd enjoy what I could of the ship for as long as I could...yep they want you off by 9, but often it's after 10 before they are physically able to get the line of folks off.
I'd just plan on a nice lunch at the airport, and some people watching, because with a 5:30 flight, you really need to be on the airport property no later than 3pm.
