Is this OK Turkish ? 

Bunlar şehirlere gittik: Miami, Houston, Orlando ve Los Angeles (sadece ben).

If you went there alone, you should say; "bu şehirlere gittim." If you went there with somebody, you can say; "bu şehirlere gittik."

That´s interesting because if that were English, it would be understood as: we went to Miami, Houston and Orlando, and just myself went to Los Angeles. Mind you, it´s not very formal.
