I saw this Viking river cruises ad on television a few weeks ago, so I thought that I'd share it. Watch the commercial and see how many Budapest landmarks you recognize. Personally, I think that it is a very nice commercial. There aren't a lot of commercials about Hungary in the media. When one comes out, it's a pretty big deal. Tourism accounts for a large part of Hungary's yearly revenue. Budapest is the third most beautiful/romantic city in Europe after Paris and Vienna. If you get a chance to take a cruise along the Danube river in Hungary, make sure you do so. You won't regret it!
