Bletchley Park is covers quite large and there is a lot of reading to be done as you go through the various area’s. I had read several books about the Park and what had gone on there during the war and was reasonably well informed before going. I still managed to spend four hours there, not even getting to the separate Computing Museum but I intend to visit again as the tickets although quite expensive are valid for one year. I bought mine online the day before which enables you to get a discount, just downloaded the ticket to my iPhone. A visit can be of interest on several levels, historical, the war, code breaking and computing. The Sunday I visited they had a Jazz singer & BBQ in the grounds and as the weather was good it was a very pleasant way to pause, listen to the music and take the weight off my feet. I found it extremely interesting and thoroughly enjoyed my visit.
