We were there 2 weeks ago.
A number of balls with boats on them at the Sand Box. Also plenty of room to anchor, which we did. The bar/restaurant looked almost done but no work observed the 4-5 days we were there.
Bitter end had a lot of work going on but still looks like they are clearing stuff. I saw no new construction so late in 2019 is optimistic even for a bar and dock.
Same with Saba but at least new construction going on but nowhere even close to done.
