Really?
You expected the cruise line to stop maintenance on the ship, because someone was trying to sleep? I am assuming this was during the day time (likely while in port), since
DCL typically would not do paintwork in the dark. If that's the case ... I fear you have priorities backwards. A ship at sea will eventually rust inward, without DAILY cleaning and maintenance. It's not like hiring a contractor to work on your home ... it's THEIR ship, and they work 24/7/365!
We've had oceanview and verandah staterooms and had crews power washing and / or painting the exterior of the ship while in port. Not an issue for us ... they're working! This sort of work is typically performed while in port for several reasons ...
- Guests are often ashore
- CM's are able to work along side of the ship
- Work can be performed with less interference from salt water
We are DCL Platinum ... often sail on deck 2 midship. I can honestly say I have never been under the gangplank, nor the galley (especially at the same time). Gangplank aside, I have found MOST staterooms are not under a noisy public room (part of the Disney pixie dust design) ... but have no first hand experience in specific stateroom ... nor have I heard any other situation since we started sailing DCL in 1999.
As for Deck 2 *seeming* to be better on the Dream ... I think that was likely an illusion.
