I've not been to Worms, but I've been to Munich a couple of times. I lived near Freiburg for a couple of years in the late 80s. An interesting time for Germany. Currently revisiting Berlin after 27 years.
I am from Bedford in the UK and currently live fairly near there. Also spent time in Coventry for university.
Bedford is a nice city what i heard from people - enjoy your Berlin trip and let me know when you are over in Munich again
