A tale of two cities: the twin-city break

Hello everyone, my latest piece of travel writing is up on Alvinology: it is all about booking one return flight and getting two city breaks, just like the way I did in Copenhagen and Malmo recently. I have found a nice list of ten cities where you can actually do this twin-city break and I hope you will enjoy this piece of travel writing! Many thanks for reading.
