I’ve stayed in Copenhagen a few times and been across to Malmo a couple of times. I’m probably doing it a complete disservice, but I’ve not been impressed with Malmo… after walking around for about 30 minutes I’ve headed back to the station to return to Copenhagen.
The Helsingborg / Helsingor trip was good fun, but if you’re on a cruise anyway then the last thing you’ll want to do is go for a ride on a ferry!
