We went last year at Christmas time, and got PP for MK and AK. We were at MK for Christmas Day, so it was wonderful to have it both because the park was super crowded, and also because it added a lot of Christmas magic to the day not having to rush around or stress about what we were doing next. We also loved having it at AK, though I know for many it might not be worth it. AK is our favorite park because we love to stroll the trails, and my kids are obsessed with doing the Wilderness Adventure badges. Having the PP let us take all of those things on our own time.
