There\'s a direct train from Prague to Dresden, which is maybe an hour away from Berlin, and that\'s about 300 Czech cowrns (15 CDN). If you\'re more than one person travelling, you can get either the Saxon pass or the weekend pass (depending what day it is) for 30 euros and take the region (slow) trains from Dresden to Berlin. You could probably get on the faster train, but it\'s typically much more expensive.Berlin, you could stay for about a week and not see everything. My friend and I covered all the main sights in Paris in 2 days. Amsterdam is probably a 2 day kind of city too, in my opinion. Prague is probably a 2-3 day trip (so pretty and cheap!), but I hear Bratislava is a tad boring.
