Perhaps I am using the wrong terminology and jumping to conclusions.
@Kuki, I am specifically referring to Carnival Miracle. The last sailing I find scheduled for her is 3/9/12 when most Carnival schedules stretch will into 2012. My original source indicated her last refurbishment was 2007. I have now found two other sources (one the same website that listed the 2007) saying her last refurbishment was 2009. That date would be in line with the "Evolutions of Fun" upgrades.
