We were on another of their "cruises from hell" in May. A PE to Southampton TA.
I wrote a very specific email when we returned in the middle of May and sent it to customerrelations@ as well bcc'ed to a half dozen Princess execs. After hearing nothing after the first month, I resent it mid-June, then again Mid-July. Getting ready to send it again in a couple of days for the fourth time.
To date I've received absolutely no response at all........from anyone.
Best of luck in getting a response from someone. Certainly better luck than I"ve had!!
