Queenstown New zealand Highlight
For a great view of the city (especially at night) go to the top of the Eiffel Tower at Paris. It also offers a great vantage point for viewing the water show at the Bellagio.
For ladies I would definitely recommend finding some slightly nicer than normal black flats... I bought some in Prague for super cheap and still wear them all the time!
Christmas Markets in Vienna are great. Buy some mulled wine (Gluhwein in German)which is served hot and is quite spicy. The mug it comes in is yours to keep - a great souvenir -but if you don't want it return it and get your €2 deposit back (Pfand).
