It would depend on your room's location/view. We just got back from a stay in the Sugar Loaf building, and of course couldn't see any construction from our room. We could see it from the boat & the monorail & I remember seeing it from the main gift shop on the 2nd floor. (We never heard any noise from it, BTW, although we were there on a weekend -- maybe they don't work on it over the weekends?) There's been a lot of discussion about this on the GF thread & some photos have been posted -- you may want to check there (probably the last 20 pages or so you'll find the info).
We didn't stay RPC, but I would think the rooms above the Gasparilla Grill area would be the least affected.
