So my g/f and I originally planned to travel to Thailand in May, but turns out the weather there will most likely be raining/monsoon season. So we decided to change it up and hit up Europe. So we are flying into Berlin May 4th, staying there for 5 nights. Then we will take a train to Amsterdam, and stay there for 3-4 nights. Then we will fly to Dublin, and stay there for 5-6 nights. If you had this trip, what are some MUST see/do things that we can incorporate? We are in our late 20s, and love WWII history, music, sports, drinking/nightlife, art, food, etc...please reddit, help us plan the best/first European vacation that we can have!

Can you provide a brief rundown of the text in within 3 sentences?
