Not having seen much of your Option 1, my comments aren’t going to be worth much. The prices there alone sort of rule it out for po-folk like me. One could say it will be cooler in the Summer but Summer runs from June 20 to September 20 give or take a few days so even that is subjective in that it might be a bit too cool in one or not too hot in the other.
So, Option 2: Your description sounds very “responsible”. Sorry, I don’t know what word to use, I just remember what I was doing on holiday in Europe when I was 20-something. You sound more like me at an older age.
Nature, scenic landscapes:
- Well, you have chosen major cities. Not a lot of either in any of
them. A bit in the Wachau Velley I guess and a bit around the
Pannonhalma Archabbey. Oh, and yes, on the way to and from Salzburg
… but … too far. If this is a primary objective then head for the
Balkans (Option 3). Drop dead stunning, great food, great culture,
great prices. You can do 4 star for 3 star prices in Austria.
Walkable cities:
- Given the size of the Prague Old Town, very walkable (in a few
hours). Same with Vienna in the Ringstrasse. Budapest has very
walkable districts where the sights are found, but because of the
size of the city you get to enjoy the old tram system as well. I
think they are a kick in the …. You know.
Cafés:
- the Austrians are going to argue with me, but at best it’s a tie
between Vienna and Budapest.
Local culture:
- I will say a tie again with Vienna. For Haut de Gamme you go to
Vienna, while for more accessible you go to Budapest. I also think
because the cultural activities don’t attract as many tourists that
they have the opportunity to be a bit more authentic in Budapest.
But just a personal perception.
When to go:
- As early in June or as late in September as you can.
Saturday: Arrive in Prague (9 AM), Sunday: Prague, Monday: Prague
For me, the right amount of time in Prague given the full length of your trip. Nice city. Very aesthetic. If you were me in my 20’s I would say “a lot of good pubs”. In the summer there tends to be a lot of college kids on short city breaks which might give you an opportunity to meet some with something in common.
Tuesday: Train to Vienna, Wednesday: Vienna, Thursday: Vienna
(possibly a day trip to Wachau Valley), Friday: Vienna (or day trip to
Salzburg)
Wachau Valley, a nice daytrip. Depending on your date it might be a bid crowded but its pretty. An option to that would be to stop in Gyor and the Archabbey at Pannonhalma on the way to Budapest. It’s on the trainline so no detour and no back tracking. Google and look at them.
Day trip to Salzburg, well, first its too far for a good daytrip, second its not that exciting in my book and third you are a day short in Budapest.
Saturday: Train to Budapest, Sunday: Budapest, Monday: Budapest
Like I said above, you are are a day short when the stops are compared to the total time you have.
