I am going to word this poorly, so I apologize in advance, please try to understand what I actually mean. California law states you must be provided the same opportunity as a non-disabled guest in a way that meets your needs. For example if someone who isn't disabled is allowed to get an unobstructed view, then those who are disabled must be able to get a similar view. This likely means a party has no disabled guests in it does not have to wait separately, the party that does have a disable guest would not be able to be required to wait separately. Now, there can be a reasonable limit on the number of guests in the disabled party due to say size restrictions, based on other theme parks, etc., it seems that number in California is considered to be 4 including the disabled person. As I said, this is actually going to be a very interesting case to see how it plays out and ramifications are going to be wide spread, as in general California leads the way in a lot of these things and other states will likely adopt similar measures.
