What interesting things are there to do in Austria?

I am making a postcard for my german lesson, so I need some places I could visit, the food and drinks they serve, some things that I could do there and a place where I could spend the night

Visit Vienna ;) - it麓s the capital of Austria.
In the city center there麓s the Stephansdom.
(a famous church in the gotic style) We have many
beautiful churches here.
There are lots of museums and theatres (old and new ones)
Don麓t forget the opera. The "Wiener Staatsoper".
Take a coffe at an old, comfortable coffeeshop. You should
try the traditional "Sachertorte" (a chocolatecake)
I would like to take a "Fiaker" - that麓s a horse carriage - around the "Ring" or "Ringstrasse" where you can see
the most interesting and famous buildings of this city.
The parliament, the university, the citypark "Stadtpark",
the "Burgtheater", the "Votivkirche", the museums of nature
and history. Spend some hours in the "Wiener Prater", that麓s
a huge fun parc. You can eat a lot of unhealthy, fat food here
and drink a lot of beer. If you like wine better, you should visit
one of the unique "Heurigen" in the surbubs of Vienna.
Make a boattour on the Blue Danube River or make a trip
in the "Wienerwald". We have a lot of forest around Vienna;)

In winter- skiing, in summer, walking and looking at old buildings, water sports and activities on the lakes.
Food? Lots of meat and pickles, dumplings and cabbage, cakes, coffee and beer.
Spend the night? Well, I heard that there were some hotels dotted around the place!
