You get more than 2, it is just 2 a day you can prebook before you go. You then book another das pass in the park for a return time, once that is scanned in you can book anotherShe may still have to stand for a while in the Lightning Lane queue, getting on a ride is not instant even with that. If she can't stand or sit then DAS will likely cover her but you only get two selections a day so if she is happy just doing that then it may work for you. Good luck!
