I have a trip coming up in November to Budapest, Hungary. I fly in the 19th and out on the 1st of December. I will be traveling by myself, so I don't know if it's better to rent a car or travel by train. I've looked into different itineraries, but nothing is set such as: Budapest, Bratislava, Vienna, Prague, Munich and back to Budapest (by train). Or Budapest, Lublijiana, Bled, Zagreb, Budapest (by car).
I haven't decided if I want this to be a sight-seeing trip or if I want it to be a lot more laid back with me hiking and relaxing in the thermal baths instead.
Any suggestions?
