A few words of advice for you fee-an-says out there:
Bringing along your bridesmaids, festive as they might be in their party hats, is a bad idea. Especially if they're still drunk from the reception.
Ditto for your horse.
Upon arrival in Paris, don't give him a dirty look and announce: "If you think you're gonna stick that little twig in ME you've got another think comin', buster!" Headaches are a better excuse and don't immediately emasculate the groom (better to do that slowly and painfully over a looooong period of time).
On the bright side, what more can go wrong?
