Days 1 (Thursday) and 2 (Friday) will be Berlin days/nights. On Day 3 (Saturday) I will be going to Leipzig but will return by 7pm. Day 4 (Sunday) is a Berlin Day. Monday I will be leaving early taking the ICE to Frankfurt.

Which welcome card and museum card (if any) should I get?

I want to visit the Gemäldegalerie, Neue Nationalgalerie, Checkpoint Charlie (museum), Berlin Wall, Pergamon Museum, Bodemuseum, Berliner Dom, and Alte Nationalgalerie.

I have a 12:00pm reservation to visit the Reichstag on Friday thrown in to this mix.

There are various choices with the Welcome Card and the Museum Cards. My going to Leipzig on Saturday ruins the 3 day Museum card as I assume those 3 days are consecutive.

So which Welcome Card should I buy? Should I get a Museum Card for the Museum Island or a Kulturforum museum card?

I know Thursday evenings from 6pm-10pm, the museums I'm interested in are free. Which museums do you recommend I choose for Thursday night? I'll grab a bite to eat in the museums.

Are there individual day cards for museums?

Whatever your recommendations, must I buy them online or can I buy them when I arrive in Berlin?

There are so many options but I don't want to make choices in which I don't get the most from these savings cards. Please advise! Thank you.
