Hi Everyone.
I just wanted to toss in a little more information about the purpose of the Yellow Access cards. They do not replace the Guest Assistance Cards in any way. In fact, they were designed to offer additional assistance to many of our guests with disabilities and their families.
If you have a Guest Assistance Card with instructions to allow you and your party to utilize the FastPass entrance at an attraction, you do not need to worry about the Yellow Access cards. You may continue to enter through the FastPass queues as you have been.
The Yellow Access Cards are designed for guests not using a Guest Assistance Card or who are using a Guest Assistance Card with instructions to utilize an alternate entrance in the case of mainstream queues. In the past, when these guests wanted to experience one of our attractions that offers Disney's FastPass, but did not feel comfortable waiting in the regular standby queue, they were instructed to obtain a FastPass. The FastPass system acted as the alternate entrance at these attractions. However, if the FastPasses were all distributed for the day or were being given out for much later in the day, there wasn't any other option-- guests either needed to wait in the standby queue or not experience the attraction.
The new Yellow Access Cards allow these guests to have another option. Instead of getting a FastPass, they can request a Yellow Access Card which will allow them to return at a time equal to the standby time. (Example: if the current standby wait is 30 minutes, they can come back in 30 minutes and enter through the FastPass Return queue.) In this way, Walt Disney World hopes to extend the extra assistance that is needed, while providing an equitable situation for all of our guests.
Personally, I think the Yellow Access Cards are a usefull addition to the other services available to our guests with disabilities. They were designed with our guests in mind and are not designed to limit access or prevent fraud.
I hope my explanation wasn't too confusing. Let me know if you have any questions - I will do my best to answer them.
Have a magical day!
