I wish only good news for your health as well.
We are scheduled to visit Turks and Caicos, Tortola, St Thomas, and Half Moon Cay. My wife Jerri will not want to do anything strenuous. I read that at half moon cay you may be able to reserve a clamshell on the beach. Jerri wants to be near the water but not take in too much sun. Any suggestions would be welcome!
