Got home from work today and there was an envelope from DCA. Inside the envelope were 2 free child passes to DCA. My family(adults only) have premium 2 park passes and that makes it even better as we were planning on taking the two kids to DCA. Called my brother and his fiance and they also received 2 child DCA passes!!. The letter enclosed with the passes states all 2-park passholders will receive these.
