I live in Anaheim, and there is no smoke issue currently.
Alas the fire in the Cajon Pass area is large and nowhere near contained. It is impact the main freeway from the Southland (LA/Orange Counties) to Las Vegas which has been closed fully at times, and might have to close again.
So yes, there is a possible of the
Disneyland area getting smoke, depending on how the winds change. Right now, the winds are change quite frequently and one of the main issues that the firefighters are dealing with, as it is hard to plan where to attack it.
But there is no real way the fire can head south, it can easily move west along the mountain rural areas, but an Urban area that has a lot less "fuel" for the fire will help stop moving it in the main Southland areas, which includes many counties in Southern California including Disneyland.
But there is still a very high fire risk in the area (what is called a "Red Flag") and the nearby Anaheim Hills and northern section of the Cleveland National Forest would more than likely impact the Disneyland area, once again, depending on winds.
