Yes, & this is what makes it bad for those that need GAC, my daughter is a Make A Wish child, we had a GAC on our MAW trip, & we over heard people make rude comments plenty of times, I have a thick skin, but my DH does not, he just wanted to leave the park.
We were able to make a second trip to Disney World for our Daughters 5th birthday, she is in remission, & she had been wanting to go back to Disney, so we decided that it was a perfect time to go again. We got a GAC again, along with a wheelchair pass for our stroller, again rude remarks, I ignored them, & told my husband to ignore them too, we were making awesome memories & celebrating our Darling Daughters birthday ( to look at my child, you would not know she has health issues). God Willing, we will be able to make another trip again, & yes for my DD, I will be getting a GAC, because she is very important to me,& this is a way for her to visit the parks. We only stay a half a day, she gets to tired.
Please think twice before you judge, you would not want to be in our shoes.
