It appears to be starting this year.

Here's the owners information from Simpson Bay;

"We are just as excited about upcoming changes to the public areas of the resort. We will be renovating the marina waterfront to make it an enticing destination for members and guests. Extensive renovations will include the removal of the model villa that currently sits in the middle of the waterfront area, and will add landscaped seating areas with charming amenities. We also plan to improve accessibility, improving the stairways and clearing out older decorative structures to improve sightlines. The marina waterfront will be more beautiful, more accessible, and will provide more food and entertainment choices for our members and guests. We will transform the marina waterfront into “the place to be” in St. Maarten. It is important to note that the members will not receive renovation assessments for these improvements – the developers are assuming 100% of the cost for the marina waterfront renovation.

We have also planned a number of beach improvements. The most dramatic change will be the creation of a new beach in front of the Villas building. We will also build a boardwalk to connect the beaches and provide easy access to a new beach bar. Again, the developers will bear all of the costs for these improvements.

Finally, we have been making many improvements you won’t necessarily see, but that will greatly improve your vacation experience. All telephone lines are being replaced around the resort, individual Wi-Fi receivers have been placed in each villa, and we are upgrading our telecommunications infrastructure to improve performance and usability. We have also upgraded the water delivery system with added redundancy to prevent outages, and have automated the water and fuel systems. We are currently improving the air conditioning system that services the Villas building."
