A disney trip planning to california/orlando disneyland

Hi guys,

My name is adrian and I am autistic who really love disney characters. I go to disneyland every once or twice a year where i can go and play with the costumed characters which i really love as i love the feel of the costumed characters when i hug these disneyland characters. in the past, i usually go to the one in hong kong or tokyo.

next year, i am planning to either go to the one in either orlando or los angelos where i can greet more characters. 

I heard that in disneyland, they do DAS card for special need guest which is a freepass card where they don't have to line up for anything. but I'm not sure how is works and does it works for characters meet and greet. I only loves the characters meet and greet so i can touch the characters while don't like the boring rides. 

can anyone give me some advice about the DAS cards in disneyland orlando or los angelos and some information about the characters meet and greet include the duration they stay in the park, what characters are there to greet, duration of the time and the location and does it works for the DAS card? Answer me for those if you had been to disneyland and does the characters meet nad greet.

I would like to hear your advice

thanks
