First Time to Europe

Please, I am in need of advice, suggestions, tips, and any knowledge to make this a bit more rational.I have decided to fly into Frankfurt. However, I do not know where to proceed next. I want to see Pairs (Eiffel Tower, palace of versailles, Normandy). Then I am not sure to stop in Brussels or skip it. I want to spend some much deserved time in Amsterdam. Then I do not know where to go then. Straight to Berlin or make a stop in Hannover or Hamburg, Germany en route to Berlin. From there, Poznan to Krakow. I really am excited to visit Krakow. I continue from Krakow to Prague. Prague to Munich and then on to Zurich for Mt Jungfrau. Finally, back to frankfurt. Problems that I have here….
1. Skip Brussels?
2. From Amsterdam to Berlin, is Hannover or Hamburg a good decision to stop for a day or two?
3. Poznan worth visiting? Do I skip it and re-route the last four stops of my trip?
5. From Zurich, I want to travel the Rhine up… Any suggestions?
6. Is there a better way to re-route my trip?

You doing too much backtracking…frankfurt to Paris then back to berlin??? Doesn’t make sense. Better to fly into Paris, then Brussels, Amsterdam, over to Berlin (skipping Frankurt entirely (frankfurt is just a business city with a big airport) and then on with the rest of your trip

Nice looking trip. I personally would try to squeeze in Brussels for a day. Lots people go to the museums etc, but I like it because it has (arguably) one of the most beautiful and overwhelming main squares in Europe. I’m also fiend for great beer and the belgian national dish of moules et frites (mussels steamed in a wine cream sauce with french fries). You can go see mannekin Pis, a very famous staute, but just a small staute of a little boy with water coming out of his penis like he’s taking a leak (was probably shocking 100 years ago, but just a tourist trap now surrounded by stores selling cheap crap)

Amsterdam to Berlin: Hannover and Hamburg are both good choices. As a big Beatles fan, I give the nod to Hamburg. It’s where they got their start. Many of the clubs they played in are still there. I also like Lubek, just north of Hamburg, which is a beautiful and hisoric port city (it’s a UNESCO world heritage site).

Poznan; Never been

Zurich up the Rhine: I’ve been researching a Rhine cruise for years but have never done it. My parents did a rhine cruise between Amsterdam and Basel and they loved it. It was pretty expensive and took about 10 days (then again they were travelling against the current which takes longer). Maybe you could do a shorter trip I.e. Zurich to Strasbourg and then get off and train it to Paris. I think the best part of the river, with all the castles etc. is between Bingen and Koblenz. Maybe you could do Zurich to Koblenz, depart at Koblenz and grab a flight home out of Frankfurt (frankfurt is a major airport hub). Hope you can fit a Rhine cruise into your time frame and budget.
