If we went to Budapest it looks like it is a 5 1/2 hour train ride
from Passau, and then a 3:40 ride back to Melk.
The 3:40 ride to Melk has a 6-minute change along the way. Now, our local train gurus say that’s wonderful. As often as trains are late, just not what I would do on holiday.
Or would it be wise to rent a car?
Some do that very well and enjoy it. I probably have close to 5 years total time in Europe now and I have never driven. And on holiday not what I would like to mess with. Just renting and returning it will take hours.
I did rent one in South Africa back when the World Cup was there … a total disaster.
In your case you will have a second country drop off fee, gas, tolls, tickets, bail money to deal with plus the cost of the rental.
Maybe think of Daytrip.com. I looked, its 295 euro which maybe isnt much more if any than the rental. They have some interesting stops they will make along the way. Ive use them in the past. Always worked well. OR, I know a driver service, but don’t know that you could price: http://www.silverwings.hu/ Ive known Laszlo for going on 15 years. Good guy, good service.
Ugh! I want to bike ride. I wonder if we are pushing a plan B? Maybe
better to cancel the whole trip, I don't know.
No suggestions on that one. But do understand.
Question: Is Budapest worth 4 nights when considering the time it will
take to get there and back?
Despite my obvious bias for the city I don’t think there are any that will question 4 nights being a good stay in Budapest. So that much is okay. As for the time there vs 8 hours total transportation time …. Again …. Sort of a personal preference but its rare to get between any two meaningful destinations in Europe in under 5 hours door to door.
I think I sent you a link to my notes and videos. Look and if it seems interesting …. You will probably be glad you went. But if it doesn’t light your fire keep looking.
