We did end up going and spent 2 nights. When we arrived at Ensenada Honda on Culebra, I called the number for Puerto Rico tourism. The very nice lady I spoke with said to keep our COVID documents handy and to have a good time.
Stayed on a ball in Mosquito Bay the first night and on anchor close to town the second night. On the second day we rented golf carts and explored the island and the town. Great time. Flamenco Beach was terrific.
