Well, they put the plywood up in the elevators that they use for luggage transfers at the end of the cruise anyway. On the walls, not sure about the floor. So that part's not really necessarily part of the re-imagining process.
The ply on the floors was to protect the deck and support the large palettes of new stuff that was to be craned on and taken to Cadiz. They also removed the inside doors to outside deck 4 on weds. In addition, they cranked up all 4 engines once we left Cozumel to just shy of 25kts. With the headwind of 17knts we spent the last seaday with gale force winds topside. Beautiful sunny day, but spray flying off the pools and the deck chair cushions blowing across deck. This was done to arrive at Port by 3:30 am, for to cargo containers to be lifted on to forward deck 5 at crew pool, before docking.
The mechanical issues are certainly part of a cruise but the contractors were doing massive work on mechanicals from day 1 of cruise -that's why they were aboard. Lots of plumbing, electrical changes. As the work progressed more and more issues continued to show up.
Most contractors stayed below, out of sight, but there were a few who every morning and evening took over deck areas with buckets of beer. Loud, rude, and impolite (the head of one company with workers told us one night that if they were his employees they wouldn't have remained his employees.) It became a regular routine for a group of us (guests) to clean up after they left since the left beer bottles, buckets (they once used an upside down plastic booster seat for a beer bucket and left that), and worst of all bottle caps scattered on deck. We made complaints to guest services about it (when I finally did on Thursday the CM pulled out a notepad filled with notes and said "we've had a lot of feedback about the contractors," and added my issues to the list.). Sadly, nothing was done until the last day when they contractors didn't appear on deck.
When they closed the arcade on weds they hung a sign that said "closed for maintenance" and then started emptying it. When I asked why no warning the cm at guest services (same one with list) apologized and said that the decision was made at corporate that morning and that they didn't know either.
Every CM (youth counselor, guest services, servers, hosts) discretely told us they had no idea what was going on and that they thought it was a mess. They also felt it was against everything they are drilled to do - to treat guests as guests.
I began the cruise as the passenger who was telling everyone to roll with it, don't let this spoil the cruise. It's all good. But over the last couple of days even I couldn't ease my way through it. The behavior was appalling. I kept hearing from other guests variations of "why don't they throw us overboard and have us swim home the last day - they don't want us here." And when they roped off the goofy pool deck all around on Thusday evening and took all the deck chairs, but ran the funnel vision anyway, I saw guests tearing deck chairs from their stacks and dragging them back inside the ropes to watch. There just came a point where people kind of said "nope - no more."
