Transportation advice: Rome-Switzerland-Reutte-Munich

3 teenage boys can take up a lot of space in the back seat, depending on age and bulk. With that and luggage for 5 you'll need a pretty big car, and cars tend to run small.

Getting the car in Germany is a better idea than in Austria or Switzerland because you will be apparently driving in or near German cites requiring an Umweltplakette and a German car will coe with one.

Since you will be on the train already I prose considering if you actually need a car at all, or for as long as you say. Since virtually all your German visit will be in Bavaria, using a very cheap "Bayern Ticket" after 9 am weekdays (with teenage boys 9 am may seem pretty early if they are like some I know) or all day on weekends may save you money and hassle. Valid on non-express trains (no ICE/IC/EC) and also valid on all local buses, trams, U-Bahns (underground trains called subways in the US), and S-Bahns throughout the entire state of Bavaria, in other words all your needs for the day. Depending on the kiddoes' ages it can be even cheaper. 26€ for the first passenger, 8€ for additional. Under 15s free - see below.

Own children and grandchildren:

Children up to 5 years always travel free of charge. If the ticket is
used by up to 2 persons, one person can take any number of own
children or grandchildren under 15 years with them free of charge.

If there are more than 2 paying persons, 6-14-year-olds pay the regular fare.

So how old are the boys?

You say that this is part 2 of the itinerary? How are you getting to Rome? Unless you are coming from just down the line only 2 days in Rome seems awfully short, IMHO.

Thanks for the great feedback, @Nigel

The boys will be 17, 15, and 13. We deliberated Rome back and forth and the boys just have hearts set on seeing the ancient Roman sights. (Not all of us are as wild about going out of the way and dealing with crowds, etc, but we've booked airfare, so we're set now!). As you can see from the full itinerary below, it's not even 2 days in Rome as we fly in early on June 4th and hope to do the Pantheon and spend time in the piazzas that night. The priorities on the 5th would be the ancient Roman sights, hitting the Colosseum early. That will be a Friday, so we hope to do the Vatican "Night Openings". It's definitely a busy itinerary: day of travel, day of touring, repeat!

I'm very appreciative for this forum and your feedback.

Hi Richard. My suggestion: skip Switzerland and replace it with mountain time in Austria and Germany. Berner Oberland is very nice, but too far out of your way. Instead, from Rome, fly or train to Munich, get your car, and use it to tour Germany and Austria, including some beautiful mountains. Enjoy your trip!
