Ha! Take *that* Wizengamot! I love this story. It's so fast and funny *and* a happy ending. I love how Harry is both articulate and sure of himself when standing up against the Wizengamot, and fumbling and semi-clueless when dealing with Snape. I love the way Snape is smart and snarky, and a little flirtatious, and brave. The sex is hot. Fred and George are, well, Fred-and-Georgish. I love that you let Fred and Hedwig live as well as Snape (and I choose to hold out hope for Remus and Tonks, as well :-) ). Of *course* Hermione is off researching something, and of *course* she manages to pull it together at the last minute. And hey, your title alone is worth points. And I'm sure they'll have a great time in Aruba.
Oh, and the flirting Patronuses (Patroni?) were great, especially the way Harry's stag was all 'WTF?!', and Snape's doe was all, 'Hey, big boy! Whatcha *do*in?' In, you know, magical, semi-substantial deer language.
