Carousel.

The Ferris wheel is a good place for a last date, because the circle describes all the stages of a relationship. At the bottom, you go into a booth together, go up to the peak, and then everything goes down again. Moreover, no matter how much you swear at the top, you still have to get out of it together at the bottom. During this time, the characters manage to piss each other off, drink, make a wish, swear, hug goodbye and even literally leave the heart.
