Delta Airlines changed my departure from New Orleans to LaGuardia from 2:30 to 5:30. I called Royal Caribbean to ask about any sightseeing tours in New Orleans prior to departing to the airport. The only tour they have leaves the ship at 9:00 a.m. and brings us to the airport at 12:00 noon. We have to hand around the airport until 5:30. Does anyone know about any tours available in New Orleans that we can take beside that? Thank you.
