We must have been on a different ship! We had a fabulous time the ship was fantastic clean and well kept. Our cabin steward couldn't do enough for us and the crew without exception were wonderful. I would sail her again in a heartbea.
Quite frankly, the only thing I would ever take on the Sea Princess would be clean, unripped sheets and bottles of bleach - have you booked? - don't, and no - I don't think you can take this instruction (I doubt the crew would give you long enough to ask the question, let alone supply a pleasant response. This boat used to be the Adonia (P&O)since its sale or re-launch or whatever it has sadly deteriorated - if I never cruised again,I would not board the Sea Princess...simply dreadful..
The above is not the same experience that we had in June 07!!!! We had a wonderful med cruise with no complaints! I'm not sure if they would have anyone qualified to give P.A.D.I. instruction but it might be worth ringing their office in Southampton to ask?
