The Circle City, because of I-465, which encompasses the entire city (in a circle!), and also probably because of some race called the Indianapolis 500 over on the west side.
I don’t know if that really is a nickname. More of a location.
Usually O-Town or The Mouse House is heard most often in Orlando.
Just got me thinking of other “central florida” names. Kissimmee/St Cloud is Cow Town and Winterpark is Rollinsville.
Houston can be variously refered to as:
The Bayou City
H-Town
and while not nearly as common, my personal favorite:
Magnolia City
During certain times of the year, we can be refered to as:
Hot 'N Humid Burg
AC Central
or City 'O Skeeters
Orlando’s official nickname for itself is The City Beautiful. I don’t see it.
Arien, where near the Hub do you live? I’m in Canton.
