NEW ORLEANS- From a decline in arrests to the number of visitors, Mayor Mitch Landrieu is hailing the Carnival season in New Orleans as a success.
    
On Thursday, the city released numbers on arrests, the cleanup and the number of visitors.
    
Landrieu also thanked city workers for their efforts at making the festivities a success. Carnival season ended on Ash Wednesday.
    
The city says the number of arrests was down this year from last Carnival season in the most-trafficked areas. The city attributed the decline to a strong police presence.
    
The city also says streets were cleaned within two hours of the end of parades.
    
The city says the Louis Armstrong New Orleans International Airport saw a seven-year high in the number of passengers traveling through the airport.
