Does anyone know when the Diamond Princess was last in drydock and what was done? Or, is a drydock in its future in 2023? We were on this ship 2017-2018 in Australia/New Zealand and it was showing its age. Thinking about booking Japan for summer 2023 on the Diamond but have been on too many shabby Princess ships - worn carpet, stained sofas, dining room chairs without any padding, old mattresses, etc. It seems that the older ships just don't get the same level of attention as the newer ships.
