I had a Sunset Savannah/construction view in the fall (basically across from the Kidani lobby.)
The only construction noise I heard with doors closed was the bulldozer backup warning beep as the bulldozer did it's nearly daily backwards drive around the building..not sure whay it was necessary for a track vehicle that can turn on a dime) I do not hink I ever noticed the noise at any other part of Jambo (like the pool, although there was exterior building painting with lift trucks at the time)
The rest of the noise was only noticable when sitting on the balcony, I was fine with it, though, because 1) I educated myself on the DIS before my trip and knew construction was possible, it did not suprise me to ruin my vacation so
2) I kinda enjoyed the once in a lifetime chance to follow the progress of a Disney construction site from my private balcony!
