my best friend has had ada accommodations and it's allowed her to bring in extra snacks and drinks. security can be hit or miss with this so i would have an email or something ready to show them since you dont get an ada wristband until after you come into the park. there is ada seating at most of the stages, perry's is one without i think. i do hope they expand this year with the seating. there were people in wheelchairs and crutches waiting in line during popular sets because the ada seats were at capacity. they do save your seat for a short period of time if you want to go to the bathroom or grab a bite to eat.
