Itinerary Check?

Does seem a bit heavy on the Prague end.

Yes, I would move one of your Prague days to Budapest. Budapest deserves equal time to Prague.

They are in their mid-20's. Prague can be very enjoyably hedonistic at that age. If that's the reason for so many days in Prague, then Vienna is one day too long.

Your lunch in Bratislava will turn the 2:37 trip to Vienna into about a 6:30 trip. With time to and from the train station and an hour for lunch in Bratislava.

Yes, you can do that. Budapest needs at least three days. Budapest and Prague are eye candies with gorgeous views across the river. They both have cafes (Vienna is IMHO #1 in that), you find sights in all three. Prague is the most walkable out of those three cities and has two medieval neighborhoods. Royal Golden Way from Powder Tower - Old Town Square - Charles Bridge - Hradcany Castle is very crowded during a day. I recommend to do it in the morning before 9 am. The earlier the fewer people. Cafes are the best in Vienna, wine in Budapest, beer in Prague.

Hi,

If I had allotted so many days for Prague, I would certainly include day trips r/t to Konopischt and another historical town/site. .

I should add that we aren't really party people. Perhaps I will move a day from Prague to Budapest then.

Probably a good idea.

Six days is Prague is too much, even it you visit places outside the city on day trips.

I would go with four nights in Prague. If you can fit in Salzburg for a day, that would be good.

At best you have 2 1/2 days in Budapest, if you suffer from heavy jet lag you will have less than that. It looks like the RS Prague Budapest tour splits it time roughly in half 4 nights Prague, 3 Budapest. Unless you have identified activities that require 5 full days in Prague I would shift one or more days to Budapest.

I will look into Salzburg, but I think we settled on moving one day to Budapest giving us 3 1/2 days to explore.
