Personally I'd say within two hours is pretty generous to define as local, so Central Florida population of 8.5ish million vs. Southern California with a population of about 24 million.Locals??
does that mean those in the general Orlando/Central Florida area?
is St Pete/Tampa local?
Miami/ Tallahassee and all of Florida local?
Adding Miami and Jacksonville and all of Florida gets up to 22 million. Miami is 4 hours away, and if we look 4 hours from Disneyland we start picking up southern parts of central California and Las Vegas. I wouldn't consider Miami local to WDW the same as not considering Vegas local to DL.
