Milli was in drydock back in Nov/Dec and went according to schedule. She was sailing again when they predicted she would. Try not to worry......and have a wonderful trip. Milli is just beautiful and the best cruise I've ever been on.
Yes they do clean up the ship where necessary. Of course things suffer wear and tear like carpets, draperies, things like that. Sometimes some paint needs touching up as well and that is exactly when the touchups are done.
