Disney's Pop Century Resort has an address of 1050 Century Drive. According to the Orange County Property Appraiser, Century Drive is the road from Victory Way to the parking lots, but no signs give the name. The only street signs, overhead internally-lit ones at the Victory Way traffic light, say "Disney's Pop Century". Someone following directions to turn at Century Drive may miss their turn.
My first inclination is to move the name to an unsigned_name field, but would this break anything such as address searching?
A more complicated case: the entrance to Coronado Springs has a name that is signed internally, but the signs at the entrance instead say "Coronado Springs".
