Please, please, please, don't ever have kids!
Its this idea that you are the king of the park and no one should be allowed to interupt your day that is sending Disney in its current direction!
To all that have children, adults, friends with issues/disabilties/challenges that need "this therapy session". Please go ahead and have it at my expense, because whether I have to wait an extra 5 mins-30 mins or whatever, I can still go away and continue my day, continue my life, continue achieving my dreams, live a "normal" life. And I can come back tomorrow and ride/see/eat what I missed today, I appreciate your party might not be handle the stress of two days back to back when a member of the party faces some challenges in the park. so by all means, at my expense, please do whatever you need to do, take as long as you need to take, to get that magical experience for not only that person by the respite and relief that you probably need as well
