Hmm...well what island are you planning on staying at this time? Or will you be hopping around?
If you're going to
St. John again, one of the
best Caribbean beaches is Trunk Bay. It's more modern with the facilities but has all of the great beach activities. Of course, you can just lay around and let the world pass you by yet again. But why not try out the
snorkeling and surfing. It's one of the most
popular beaches of the Caribbean and a favorite among cruise-ship passengers.
