I can 100% confirm BEYC will be open in some capacity before Christmas. They are going to have bookings for Marina and Mooring balls available through their own website. How much and what F&B is open is yet to be determined.

They have two of these "over water bungalows" near completion if not already done. They are directly south of the new Quarterdeck Marina office and bar. I personally hate the location (no privacy, looking right at the docks) but yeah. They're there. There's just not as many of them as shown in the renderings in the articles
