We had 17 on our last cruise and 20 looks to be the same as the rest of them. You are located on the private lagoon area vs the large open water that everyone else is on but you can walk over in just a couple of minutes down the beach to that area if you prefer it.
If you dont want to walk to lunch or the restrooms, they had a golf cart shuttle people back and forth as necessary from the cabanas that were farther out.
I think they are slightly closer together and the landscaping is not as mature yet, so you are not as secluded from your neighbors as you are in the lower numbered cabanas. Here is a photo of the new ones.
