We are another family the loves Philharmagic! Multiple times on every trip!
One of our favorite things to do as a family is grab some fresh caramel corn from Karamel Kuche after Illuminations on an EMH night, sit on a bench, and watch them pull the barges off the lagoon. It's really relaxing, and we don't feel a need to rush back out. The caramel corn is the best on the planet, and the music plays until they are done putting everything away. It's great, and it isn't something we would have ever planned or even thought to do. Now that we did a few years ago, we make sure we do it on every trip.
