For me at present there are two:
Germany - Dusseldorf, Aachen, Kaiserslautern and Munich but not Berlin
Sweden - Malmo but not Stockholm (this should change soon)
Some other countries which fell into this category in the past were:
Canada - Winnipeg, Toronto, Saskatoon, Guelph, Niagara Falls and other places visited before Ottawa
USA - Chicago, Rockford, New York, Denver, Boulder, Newark, Richmond, Philadelphia and Baltimore visited before Washington DC
Venezuela - Puerto Ordaz, Ciudad Bolivar, Margarita visited before Caracas
Spain - Barcelona, Tenerife, La Gomera, Ibiza, Mallorca, Benidorm and Gran Canaria visited before Madrid
The Netherlands - while I connected through
AMS I did not leave the airport but then visited Vaals and Drielandenpunt before properly visiting Amsterdam 5 years later.
