Tips - do NOT drink the Mozartkugelpunsch that they sell outside Schloss Schonbrunn, but DO try the Mozartpunsch that they sell outside the Natural History Museum. There is a photoautomat booth in the Museumsquatier. Wrap up warm. Buy one mug and use it all weekend or you end up with a bag full of mugs to take home with you. And the Belvadere isn't worth 11euros (unless you like Klimt I guess). Also, Lebkuchen. Buy all of it.
I do of course have several rolls of film from this and my trip to Paris still to process, but its Christmas and the money I would spend on that is being repurposed to spend on roast dinners and presents for my kitten.
