Riddell's is fun if short at about 5800 yds. There are a couple holes along the bay that are nice.
Belmont has been recently redone totally (when I was there in 2003, the course was entirely dirt). The website makes it look much more interesting than it was, beautiful and very "Bermudan" if nothing else....
I've played Tucker's Point as well, and I think Port Royal is better. TP is pretty expensive and tougher to get on, and has a few holes that will leave you scratching your head.
