We were on Serenade from July 17-24 and while onboard, I left two (stamped) postcards with Guest Services to be mailed to Canada. Neither has arrived yet. One is a no-big-deal "having a great time, wish you were here" note, but the other is a more personal note that I truly wanted to be delivered. This might be a long shot, but has anyone done something similar and did your mail ever make it to its destination?
