Hey, howdy, hey, Jesus!
Yeehaw! Your nephew's first visit to The Happiest Place on Earth is sure to be a rootin', tootin' good time. Thank you for helping to make this happen for him.
I'm very grateful for the way that Disability Access Service (DAS) and other accommodations have helped to make our visits to the Disneyland Resort manageable and magical. Eligible Guests with a developmental disability or similar condition may register up to 60 days in advance of their visit. Up to three additional Guests in the same party may be linked to DAS, for a maximum total party size of four.
What I recommend for parties that are larger than four is to look into other accessibility services available at the Disneyland Resort, including accommodations for accessing attraction queues such as Attraction Queue Re-Entry or Attraction Queue Meet-up. You can discuss a plan for an Attraction Queue Meet-up with a Cast Member at an attraction queue entrance. They will help arrange for one part of your group to enter the standby queue while your nephew and designated caretakers take advantage of the space and time they may need outside the regular queue so you can all meet up later at a designated location in the attraction queue. Be sure to have mobile phones or other means of communication between the part of your group in the queue and your nephew's group to coordinate the timing of the meet-up at the designated point in the attraction queue.
Tony's Tip: The Disneyland Resort is an amazing, magical place. In such a magical place, there may be times when sights, sounds, or other stimuli may be challenging to some Guests. I find it helpful to have a plan in place to help avoid or work through issues that may come up. For example, take a look at this guide to sensory experiences at the Disneyland Resort for a quick and easy reference for possible triggers so you may anticipate and mitigate for or avoid them altogether. I also recommend reviewing page 10 of the Accessibility Planning Guide for a list of quieter locations where an overstimulated Guest may rest for a while if necessary.
I hope you and your nephew have a magical time at the Disneyland Resort, Jesus. We'd love to hear how things go for you. Or if you have any more questions about visiting the Disneyland Resort, just remember that "you've got a friend in me" and my planDisney pals. As fellow Guests like you, we are eager to help in any way we can.
See ya real soon!
