Hi there, I'm looking for some advice. I'm a British passport holder and am currently planning on travelling to hamburg then getting the train to Copenhagen after this. How does it work with passport stamps?
I know I would get one on entering Germany and on leaving Denmark but would i need an exit from germany and an entry stamp into Denmark as well? Just don't want any hassle when we're away ideally.

You don't get any stamp between Germany and Denmark as they are both Schengen countries. That doesn't mean you passport won't be checked, it may be but it won't be stamped. It will be stamped again on exit from Schengen in whatever country you leave from.
Remember your British passport can't be more than 10 years old, regardless of what the expiry date is, and of course Schengen rules apply to British passport holders now.
