The expansion club host fellow newcomers New York City FC at the Citrus Bowl in downtown Florida on March 8 and are gunning for a sellout crowd of 60,000.
So far the goal of the Florida outfit appears likely as they need less than 20,000 to reach their target with a little over three weeks remaining.
Regarding the '#FillTheBowl' campaign, Orlando City president Phil Rawlins said: "Orlando City fans have responded in overwhelming numbers since last Saturday and the milestones continue to fall as we approach the history-making season opener.
"Three weeks remain and we are within reach of our goal to #FillTheBowl! Orlando and all of Central Florida have embraced Purple Pride.
"We are going to show the nation on March 8th why we are the 'Soccer Capital of the South.'"
