How many islands have you been to?

[MarkD]

I am not counting any of the islands that I merely drove across, like Yerbe Buena Island or all of those keys in the Florida Keys between Key West and the Florida mainland. There's no point in counting those islands because I didn't set foot on them or visit them. (There are three islands that I've been to but do not remember their names, I just remember what country they belong to.)
My answer to the poll is 21-30, because I have visited 25 islands (that I can remember).

United States and territories: Santa Catalina, Theodore Roosevelt Island, Key West, Sanibel, Captiva, Hawaii, Oahu, Kauai, Long Island, Manhattan, Staten Island, Wizard Island, Puerto Rico, St. Thomas.

International: Nassau, two other islands in The Bahamas, Mykonos, Rhodes, Crete, Santorini, another Greek island, Tahiti, Moorea, Bora Bora.
