I am looking for travel ideas for approx 7 days in the third week of April. I know the weather in Europe during this time may be unstable. Thus, I would like to plan my trip around areas where there are sightseeing spots for sunny days, as well as thermal baths for cloudy/rainy days. I know the famous Carlsbad baths are near the German border, but are there ones closer to Brno? I went to Prague before and have heard it's now overrun by tourists from all over the world. So, Brno appeals to me as it's still not that well known (yet). Plus, it's a hipster coffee city.
I won't have a car and therefore will reply on public transit.
