Lectura de todo aunque el temario es bastante pussy , hoy rindo Literatura inglesa del traductorado . <| sep |> I did a handful of those cities Berlin , Budapest , Vienna , and Prague during the holidays last year . As a general note , you are far enough away from Christmas that I don ' t think you should have too much of a problem but you might want to double check the hours and opening days for anything you ' re going to just to be sure . Here ' s a couple tips for each cityBerlin There ' s basically an endless assortment of museums here if that ' s of any interest . There are a variety of combo tickets for the museums on Museum Island . The Pergamon was especially cool there . I also liked the German Museum of Technology if you ' re into that sort of thing . Check Point Charlie is worth a stroll through but it ' s very touristy . You can climb the stairs to the top of the Victory Column for pretty cheap and get a nice view of the city . Go for a stroll through the Tiergarten , you could even combine that with the Victory Column . The Holocaust memorial is impressive to walk through as well . I was in Berlin for 3 days I think which was not nearly enough . Budapest It was super foggy and overcast the whole time I was there which kind of dampened the experience but I think with better weather I would have absolutely loved it . If you haven ' t been to CentralEastern Europe before , it will be quite a change from Western Europe and certainly Berlin . I try to avoid having to deal with public transport if possible but I would say Budapest is just on the edge of what I would consider a walkable city . If you ' re staying in Pest the East side of the Danube , you can do a day walking to Buda , hitting the Citadella , the Fisherman ' s Bastions with awesome views of the rest of the city , and the Hospital in the Rock which was a really cool tour of a war time hospital built into the hill . If my memory serves correctly there ' s also a church in the rock in Buda but that was less cool . The Central Market Hall is very iconic and fun to walk through , and there ' s a neat street food market on Kazinczy Ulica . I didn ' t go to any ruin clubspubs but if that ' s your scene you should hit up one of those . I remember the Christmas Markets in Budapest were really well done and there were 3 or 4 I think throughout the city . Vienna Vienna at Christmas time was amazing and probably one of my favorite cities on that trip . I did Vienna before going to Prague and preferred it to Prague , but I think I ' m in the minority there so take that for what its worth . The architecture in Vienna is really incrediblejust walking around the different neighborhoods is a lot of fun . The Christmas Markets here were secondtonone , especially the one at Rathausplatz . The Naschsmarkt is also worth a visit and if you stay at Wombats there you are literally on the same street as it . There ' s a fun Austrian restaurant called Centimeter that had pretty good food . A lot of the sausages and stuff are sold by length . There ' s the Kaisergruft which is the Crypt for all the royal graves . All the churches are as amazing as you would expect . The Freud museum was a neat couple of hours if you ' re remotely interested in him . You should also check out one of the Palaces . Schloss Schnbrunn is the most famous . It was really pretty and neat to walk through but I went on Christmas day and it was miserably crowded . You shouldn ' t have any problem there . Prague Like I said above , I didn ' t love Prague as much as everything I had read led me to believe I would . I think part of the problem was going during the days in between Christmas and New Years which must be a popular travel time because it was miserably packed compared to everywhere else I went on that trip . There are a lot of cool breweries in Prague . Pivovar U T R was my favorite I think . Prague is another fun city to just wander around . I don ' t recall anything specific that I saw there that stood out . If you can manage a day to do so , you ABSOLUTELY should make a trip to Kutna Hora . It ' s about ~ 1 hour on the train from Prague and the main feature there is the Sedlec Ossuary , a church decorated with the bones of some 50 , 000 skeletons . It is unbelievable to see and was definitely a highlight of my trip . Other pointsRe sim card Can ' t help you there as I ' ve never gotten one while travelling . Like you said , finding one that will adapt to all the different countries will probably be difficult . Your best bet might be payasyougo ones in each country . On the BudapestPrague route , I really loved Bratislava in Slovakia . It ' s super close to Vienna and you could probably even do it as a day trip but it definitely seemed like a hidden gem that people seem to skip when they do this sort of Central Europe trip . Amazing food , not very touristy , and a cool mix of Communist and European influences . Let me know if you have any questions . Sounds like you have it pretty well figured out . This will be an easy trip to do solo ! Edit Some bonus picturesVienna from Schloss Belvedereand the Sedlec Ossuary
