For me personally, it was getting engaged in the castle (just one of those amazing life moments that I will always cherish) and pushing my oldest daughter down Main St. USA in her stroller when she was 3 months old. I'd gone so much a child and teen, it was a big moment going there as a parent.
I used to say Wishes, but that's over now. HEA doesn't have an emotional moment for me, as a previous poster also said, which is really too bad.
