Robert, I agree. Only because of that Seven Seas Society introduction letter did I think it was just sent to us. Since you have not yet cruised, maybe it was because you once planned to and recently, booked again? Don't need to preach to the large choir of loyal passengers.
I often get e-mails sent from thecampaign (something)...com from both Silversea and Radisson. Do they use the same ad/marketing agency? I was told on one of the ships that they use the same recruiting agency in Asia to hire personnel.
