When we were there in May, we showed our GAC at the entrance to the princess-fairies lines. We were given a card with a number and directed to the waiting area outside of the exit. At some point a CM would come out and escort us in through the exit. It was by no means a short wait, but it provided a less crowded waiting area. Is this no longer being done?
That was what we did in May, but whether someone is able to do that depends on what accommodations they need. For example, someone with a GAC that says they need to wait out of the sun, in an air conditioned place, or avoid stairs, would not get the accommodation of waiting outside of the regular line for the Fairies or Princesses. Since the regular line provides what they need, they would not need any other accommodation.
GACs are only used for characters inside in permanent locations. They are not used for outdoor or impromptu character greetings.
In my DD's case, she had previously been to see the Fairies on another trip when we did wait in line. This was very challenging for her; she can't walk and uses a wheelchair, which was not a problem because the lines are wheelchair accessible. In addition, she has multiple other challenges, which is why we get a GAC for her and use it only when she needs it.
When we waited in the regular Fairy line, the biggest issue we had was that most of the guests waiting for the Fairies had one or 2 of their party waiting in the line and when they got almost to the front, they called the rest of their party to join the line. So, there were constantly people coming from outside and squeezing ahead of us in line. THis was very difficult for DD as her wheelchair was getting bumped all the time (which she doesn't always cope well with).
The next time we came to the Fairies, we explained our difficulties and showed DD's GAC. The CM gave us a card with a number on it and were told that we would wait in the seating area by the exit until a CM came out to get us. We were also told that our wait would be approximately the same as if we had been in the line; we just would be waiting outside of the line.
Part of our wait was in that seating area and part was standing right outside of the exit for the Fairies. I kept track of the wait and it did turn out to be about the same as the posted wait.
If we had wanted to see the Princesses, the posted wait was much shorter (I think less than 15 minutes). DD did not want to see them, but the CM told us if we did, we could either wait in line or the CM would give us another card for the Princesses.
Definately not avoiding the wait, but the waiting area did meet DD's needs.
