For us it was the castle. But that said, one of the cool things about it is walking around the park in princess get up. The CMs often go out of their way to acknowledge that there is a princess amongst them. We were on a mostly empty bus on the way home and they even played a special announcement that everyone had to behave because we were traveling with a Disney princess (me, being a space cadet at first was like 'What? Where?'). Other guests are nice too - we actually ended up in line with someone after our appt that we had been in line with before. She remembered our girls and oohed and ahhhed over the transformation. So it does make the day a little more special and sprinkle a little pixie dust. But they use enough product that the hair will last a day or two so you can dress them up for a park day the day after if you want.
