Subject: train from Brussels to Berlin
Hi Margo, if you donīt mind changing trains, a good option would be travelling from Brussels to Cologne and from there travel to Berlin with the ICE (the German high-speed train).

They only have the prices for the German trains, but I donīt think that going by train would be more expensive than a one-way flight :)) Also, maybe if you mention that you are a senior when buying the tickets in Brussels, you might get a discount.

The public transport in Berlin is quite efficient, and there are plenty of things to do and see in and around, from conventional museums to avant-garde galleries. I think you will enjoy it. As you mentioned the Jewish Museum, here you can find the website :
