On our Sept.06/22 Emerald cruise, the Q&A with Capt. Lye said that she was the 1st ship of that class to have received the upgrades to the buffet area etc and is now due for further upgrades to cabin lighting etc and routine maintenance. He didn't elaborate much except to say that one of the biggest jobs will be to replace the tile decking around the pool areas which was an embarrassment to him.
Emerald was in very good condition when we were on with few signs of wear and tear.
