Ok, I go about once a week! I'm a premium annual pass holder, and have been for 8 years. Born and raised around the park I know lots of tips about the park. I would suggest that if you would like to be an annual pass holder, go for the premium. That is if you are going to go often. Parking can get expensive! and so can food Etc. With the premium you get free parking and save 10 to 15% on hotels, Restaurants, and stores. Sometimes you can get 20% off of things. You also get exclusive offers that nobody else can get.
It's nice to go whenever I want without worrying about block out dates. So, if family members are visiting and go on a Saturday... I can go too. I'm not blocked out on that day. Some of the other passports have Saturdays... one does not allow you to go on Fridays or Saturdays. The premium passport is well worth it.
Disneyland is pretty accommodating to those who have disabilities. They have wheel chairs and electric wheel chairs for rental. I would suggest that if you want an electric wheel chair... Go early! The sell out pretty quick and Disneyland is very limited to them. They also have stroller rentals for a reasonable price! It's only $7 for the entire day. Much easier than loading yours up and dragging it around. They are pretty nice, but I would not recommend them for infants. They are the jogging type strollers. Have any Disneyland questions? I'm the one to ask! Lol
