We're back from a 9-night stay, 5/29-6/7. The noise was not bad for us in Aruba Building 55, which was the closest to the construction at the Riviera. The main noise source was the Riviera; expect that to remain the case until it is completed. Next was the expansion and refurbishment of Old Port Royale. It was not bad while we were there and while we used the pool, which is open and in great shape. Other than adding a 4th gondola pylon while we were there, there was nothing much going on at the Riviera Skyliner station. There was lots going on at the Main Skyliner station, but it wasn't very nosiy when we ate at the new Spyglass Grill in Trinidad South. Those who stayed at Jamaica could give a better answer, but it didn't seem very noisy. They also started construction on what seems to be a 5th gondola pylon in Jamaica's parking lot, but this was fairly far away from any of the buildings, right up next to the roadway.
There are Island Markets for snacks in a number of rooms throughout the resort, with Coke Freestyle machines also replacing some ice machines at limited locations. These expand your resort mug drink options into the hundreds, and are available 24/7. The new Quick Service Counter restaurant, The Spyglass Grill in Trinidad South, offers breakfast lunch and dinner. It is covered, and next to the quiet pool in Trinidad South. It is open air and the food is good. They had a TV there, on the wall, set to Disney Junior while we were there, and plenty of ceiling fans with a pleasant, open-air view of the south part of Barefoot Bay and the new Skyliner Station (construction site).
The food tent at Centertown offers breakfast and dinner buffets for the price of a quick service meal on the dining plan! The dinner buffet has some nice Caribbean twists, and competes well with any other buffet at WDW. Even if you're paying cash, it's still a great savings versus other dinner buffets. Lunch is more basic quick service fare, but still good.
So, construction: Not bad. Further, rooms are all refurbished, and compare well, amenity wise, with deluxe resorts. Also, the Caribbean Cay Island in the middle of Barefoot Bay acts as a sound barrier to construction at the Riviera and Old Port Royale. Trinidad North is a very good place to be these days. Food: Very good right now. Pool is open and great.
It is well worth staying at.
