As for getting around in Rome, it's really easy. You should be able to do most things off the metro lines. Just remember the names of the 4 termini and it's easy. There's only red & blue & they intersect under Termini. Forget the trams, and busses are a bit of a cattle market unless you're used to cities. Most of the stuff in the centre you'll have to do on foot, so have solid shoes. If you are visiting the churches, make sure your shorts cover your kees and your shoulders are covered! As for Frankfurt, Never been there, but as with all German cities, the trams will be the best way of getting around. They're OK with English there. When it comes to Vienna, the only way to get around is tram or underground. Even though it's a small place there are 5 underground lines, U1,2,3,4 and 6 - Beware U6 is often mistaken for a tram line! Then all the tram lines radiate out from the ring (where tram lines 1 and 2 and the U2) do circuits. Busses then go from the ends of the tram lines further out. There are travel cards, when I lived there 20 yrs ago there was also a 7 day ticket strip. Beware of the door handles on the U1-4 though, we always used to play tricks on newbies to the city and let them stand in front of the doors at a station; they don't open automatically! You need to hit the handles outward! There's lots to see there. As well as the other things I mentioned earlier, there's the Strauss memorial, natural history & art museums (both on the inner ring, which was the line of the original city walls). For coulour & flavour, visit the Nashmarkt, a market about a mile long, from Karlsplatz on the U4/U6 heasing West towards Schonbrun - a must see palace (don't forget to go up the hill to the Gloriette). And if you want a great cafe, try the one run by my former bosses on the corner of Getreidemarkt (where I used to work) just above the underground stop. Then there's Belvedere Castle, the whole length of the Donau Insl (Danube island), the UN building, Stephansdom in the centre of town (don't forget to walk round the back & look at the carvings & underneath are Roman remains) Shopping on Karntner str. & Graben. The Kaiser hof (palace) and experiment with the ice cream places - we used to go on ice cream crawls - the most I ever coped with was 6 stops in one night! And then there's the Prater stern, an ammusement park - go on the wheel! and don't forget Gustav Klimt's house, just off the U3.
