I'm back and said I would post photos of the Lagoon View room we were upgraded to. This is room 8145 in Boca Chica, it has 2 balconies, one facing the lagoon with a MK view and the other facing Narcoosies. It looks like the rooms above would have the same layout.
Here's the view at night with the electric water pagent. The castle (lit in purple) and space mountain are in the background. There is a tree in the view, this is the ground floor so we were kind of under the tree, but could sill see most of the fireworks show.
Because its a corner room the entrance way curves around. The closet is to the right here, bathroom in front when you enter. That gave us a nice area for the double stroller, diaper changing area, and room to get the kids ready near the closet. It felt very spacious and organized to me, and I'm kind of an organization freak.
Doorway to the main area
Past the bathroom area there is a table and 2 chairs and 1 door to the lagoon-facing balcony. This area seems to be additional to what's in the usual rooms
And finally the rest of the room, with the regular sliding door balcony facing Narcoosies. This is what the room looked like after turn down.
Also from this thread I had the impression the beach was completely blocked off. Not the case. Behind the kids splash pad there's a wide area of beach open, the outer buildings are just to the left in this picture, the construction is to the right. My son playing on the beach:
We were not bothered by the construction at all. The only time I noticed it was walking back from Poly, and that was in the evening so it was quiet. We spent some time at the splash pad but the water was so loud I didn't notice if there was noise from next door. I really wouldn't choose to stay somewhere else based on the construction at this point, I feel its isolated from the resort and the improvements to the main areas are already done and can be enjoyed.
