Changes

As the next destination for your trip I recommend Budapest. There is a daily night train that runs from Munich to Budapest, which leaves late in Munich, and drops you off early next day in Budapest. There have been some changes lately in the train system, and to book tickets, you'll have to do this via the Hungarian train company. Unfortunately, their web site is only partially in English (they're better in German), so I recommend someone helping you with those tickets as soon as you know the exact date. At the latest, I recommend asking the Hotel staff in Munich to help you out as soon as you check into your hotel there. The train name is "EN 463 Kalman Imre", get yourself a cabin for two adults, and you also may qualify for a senior discount. The train leaves daily at 11:35PM in Munich, and arrives at 9:24AM in Budapest-Keleti. If you wanna try yourself, the web site is: https://www.mavcsoport.hu/en. '''Correction:''' I just noticed that the German rail road website now again accepts reservations for this night train. Their english support is much better. See if the following link works for you: https://www.bahn.com/en/view/index.shtml The price for two adults in their own sleeper cabin is around 270 Euro. This may sound steep, but remember that this substitutes for a hotel night and the transport cost (and you save a day). I recommend using the night train, because it gives you 2 full days on either side of the trip to do something, instead of killing a day with travel. However, via the 'bahn.com' link, you can also book regular train connections to Budapest.
