Answers about Germany
Certainly Cathy - tell me more, much more.
Please accept my abject, groveling apologies for my inordinate delay in replying to your question. This has been due to numerous causes that I have only just overcome. Needless to say it has caused me the loss of clients.
My speciality is Berlin but I have conducted tours elsewhere. These include Oranienburg (for the former Sachsenhausen concentration camp), Potsdam (for the World Heritage site of Sanssouci palace and park) Lutherstadt Wittenberg, Dresden, Munich and the Neuschwanstein castle). I conduct walking tours, using public transport where appropriate. I do not do "drive-bys".
I hope this helps but quite understand if you have made alternative arrangements after such a long delay.
Is the Octoberfest organized only in Munich? Are there any museums to explore and what other main tourist attractions are there to see in Munich? Are hotels expensive in this city?
Yes the Oktoberfest is a Munich event that takes place in September each year. It is extremely popular and you might find it difficult to book a hotel if you do not do so immediately. The best time to visit is on a weekday in the early afternoon as in the evenings the tables are pre-booked. If you are not seated you will not get served. As for museums and other sights - there are loads of things to see and do. Get a good guide book before you go.
I can definetly recommend the following museums all in Southern Germany. I have been to all four and they are exceedingly impressive.
Mercedes Benz Museum
Another Highly interesting museum is this place with hundreds of vehicles (and everything else)
Bear Tours Berlin
To visit the factories you should approach the manufacturer direct. They do offer tours of an educational nature but you need to get in early as they are very quickly taken up mostly by schools and colleges. Here in Berlin I know of two museums with extensive collections. In Munich BMW have their own large museum that includes motorcycles.
