My husband and I are going from Prague to Vienna and Budapest. We just booked the Das Tyrol hotel in Vienna. Anyone has comments to share? We plan to stay three days in Vienna. What would be the best way to get from Prague to Vienna? Then from Vienna to Budapest we have heard many suggest a river boat? Any suggestions on ways from Vienna to Budapest as well as hotels in Budapest? Someone mentioned the Hilton Budapest - Castle District? Any reviews on that? Or is it worth going with the Four Seasons? Thanks!!

3 nights in each city? Is that doable?
