you cannot enter the Dome without a reservation
the East side Gallery the Brandenburg Gate and CC are not exactly in the same location.

I think you might find 10-15 minutes inadequate for places like the CC museum should you decide to go inside that.

You can also do some shopping in Potsdamer Platz at the Arkaden (behind the Hyatt Hotel)

For the KaDeWe consider visiting and perhaps even eating, perhaps lunch, in the food hall; pricey but considerable choices.

Danon- I already have a reservation and I will be purchasing the Welcome Card so will get unlimted free travel.

Dukey1-I doubt I'll be visiting museum, but cc is a 5-10 minute walk from my hostel so would be able to find time to visit one evening if I wanted to return.

Yeah visiting Potsdamer Platz I intend to finish any shopping off and yes I've read about the Arkaden will be visiting there too

KaDeWe-I've read about the magnificent food hall there and can't wait to see it for myself, I would love to have lunch there but overall what would be a average price to expect to pay?

Thanks

From looking at your itinerary, perhaps you and I have different interests, but I would recommend visiting at least a few of the world-class museums in Berlin, such as those on the Museumsinsel (Museum Island). The Pergamon Museum is especially outstanding. I also think you're trying to cram an awful lot into the first day. I'm not sure what you mean by the "Jews Memorial." If you mean the Memorial to the Murdered Jews of Europe just s. of the Brandenburg Gate, be aware that there is a museum beneath the memorial which is worth much more than 15 minutes. You may want to consider spending less time at the Potsdamer Platz. Unless you want to do a lot of shopping or visit the film museum located nearby, you can walk through the complex pretty quickly.

Thanks for your feedback just_wandering, and yes I think it's the memorial to the murdered jews of europe, and actually I'm not into big historic museums like most people who go to Berlin are, hence why I'm finding it difficult to get reccomendations that I am interested in. I probably will go and have a little look at the museum below the memorial but would save that to go back to as either a back up or one of the top things to do if I have any spare time on any of my days.
Thanks for the advice though

Even if you are not keenly interested in what you are seeing, I don't think you can tour the Reichstag Dome in 15 minutes. And if you are going to be going to some of these places for only 15 minutes, pull out a map and see which ones on your first day can be moved to other days as part of traveling around the city. Some of your first day has you flipping all around town.

I don't know why you are going to Madame Tussaud's if you are not interested in history. Unless Berlin's version is wildly different from all the others, it consists of wax models of historical figures. There will be some German movie stars mixed in, but if that's what's drawing you, maybe you'd rather go to Berlin's small movie museum.

Looking at your interests, my advice to you would be to consider investigating Berlin's night life, in all its variety. Rather than getting up early in the morning to pack your days with miniature railways and zoos and other things you can see anywhere in the world, why not stay up until 2 in the morning seeing theatre and live music in Berlin? That's unique to where you are going, and sounds more lively to me than a lot of museums which, while they aren't historic, are still just museums.

There is no average price at KaDeWe. There are many unique eateries and you can order anything from a snack to a full meal Our favorite is Fischkutters and we spend about 75E for two meals with wine and water.

Getting to the East Side Gallery takes a bit of time. I went there on my first day and between getting there and back and walking the entire length of it, it was 2 1/2 - 3 hours. Well worth it, but build that into your estimates. Topography of Terrors, even if you just look at the outside exhibits, is worth at least an hour. You'll get nothing much from many of these sights if you limit yourself to drive-bys.

The German History Museum and DDR Museum are missing from your list. I grossly underestimated both in my planning and wish now I'd gone to them earlier in my stay in Berlin. Both are "interactive" as you say you like and cover history extremely well without being dreadfully boring. I only had time to do the 1914-present in the German History Museum and wish I had more time to do the rest.

I recently wrote a trip report on all this, if you click my name it should be at the top of my posts.
