Berlin planning

We are planning for our trip to Berlin while Dale is here. I bought this great book to help guide our way. there really is so much to see in Berlin over a 100 museums. InSight makes the best travel books, with pictures and all, I have some on a few places now. There is a zoo there that is suppose to have a nocturnal section underground that is really amazing. A guided trip on the river Spree. So many monuments to see. What to do. We have our tickets on the train bought. and place to stay booked. here is the link to the place we are staying.
