I've never put my kids in PJs to go to the parks, but I have definitely showered them, put them in PJs, and then walked down to watch the Electrical water pageant. For me, it was a timing thing. The show didn't get to WL until ~9:30, but my kids needed to shower before bed, and I didn't want to make them shower at 9:45. So, I used the time before the show to shower them, and then I wasn't going to put them back in their dirty clothes. I understand that their PJs were not hospital sanitary after that, but I didn't feel like they were particularly dirty? And, I guess I'm not that bothered by them sleeping in "dirty" clothes - they napped every day in their clothes that they had worn all morning and gotten paint, food, dirt, mulch, etc. on. I guess if they spilled an ice cream sandwich on it, I'd change the PJs. I'm thinking this is what the parents who bring their kids to hte parks are thinking? And, I remember when my DD was very little and we stayed at POP Century. The trek back and forth from MK was a ridiculous waste of time, and every time we went home she fell asleep on the bus in my husband's arms. I can see how parents staying there would prefer to pack PJs so that when their kids fall asleep on the ride home, all they have to do is put them in bed instead of changing them?? Not saying I would do that, but I can understand the logic.
