I remember when I first saw that scene I was nervous that she wouldn't want "to dance with him" that she'd want to wait, like in the beginning of the episode...but of course she didn't want that, and she wanted him. I was glued to the TV when they kissed, I thought it was so hot. I wanted it to flash to the future and show them with kids and what not...of course it didn't, but I was happy with the closure we got in that scene.
My sister told me that when they first aired the episode, after the dance, when they all got in the group hug, you actually heard the director yell cut, and that was the very end...which I think is cool, I wish my sister had kept that on tape.
