My DH received the same letter/ survey. I noticed that the choices described in the letter do not coincide with the choices in the survey card( the number of nights is off). It doesn't look very professional.
Are they having trouble filling their PG cruises? I receive at least one e-mail a week touting PG cruises and also receive literature very frequently on those cruises. Compared to their other destinations I would say we get double the number of promotional material for the PG.
