@wdwmagic. Thanks for the great overview.
Here are a few other surprises, or hidden areas, that I found.
The plaza at the back of Gran Destino Tower, overlooking the lake, has a large expanse of artificial turf and a long, wooden seating area, with colorful tiles on the back of the seating benches.
Edit: While some may cringe at the artificial turf here, it was installed in the "back yard" of the Boardwalk Resort about two years ago and is very successful. The original grass in the Boardwalk Resort area was hard to maintain and muddy after a rain shower. Now with artificial turf, families actually picnic there, and the kids love running around there in the evening.
In one corner of the back plaza, there is a fire pit.
From the top floor lounge balcony, here's the view of the Gran Destino Tower entrance. The fountain in the front is still being installed.
You've already seen the high-tech elevator touch screens in the elevator lobbies. After you select the floor, the screen changes to show which of the six elevators (A through F) will be arriving, and which direction to turn, from your current position, to see the elevator opening for you. Of interest, once inside the elevator, there are no push buttons to select another floor or to change your mind.
On the second floor lobby (check-in level), at the north end of the lobby, there is an opening to this "reading room" with a plaque on the wall. Looks like a "board room" with no door.
Between the indoor walkway between the original check-in lobby and the new Gran Destino Tower, there is a side door that leads to this patio space between the buildings.
