Ann,
While I was in the doctor's office, I read a magazine article about beautiful beaches & they mentioned three in Hawaii: Lanikai in Oahu http://www.hawaiiweb.com/oahu/beaches/lanikai_beaches.htm.
Hulopoe in Lanai http://www.bestplaceshawaii.com/tips/10_best/beaches.html
& Kaanapali on Maui http://www.hawaiivtmaps.com/VTpreview/blackrockvtp.html
