Not restricted, but I'm sure the new condo/hotel will enforce rules for the beach area. As in "no glass,.etc". That's good. right? Maybe a lifeguard. That's good. right? And I guarantee you they won't be dumping raw sewage into a shallow trench . That's progress in the right direction for a developing country.
Besides, I think the vendors had a pretty good run. The landowner was extremely gracious towards them, for many years. The vendors should be thanking that family, not getting ready to riot because the owner wants to use their own property
Turning Sosua beach into a generic beach for the rich, just like many of the others in the Caribbean. While what you said is true, it sad that another beach turns into a corporation. Like I have said, I have seen it happen to other beaches around the Caribbean....it never turns out well for local people. It is what it is, the people lose again.
