My boyfriend will be scuba diving near Koloa Landing on Tuesday morning from 7:30 until 11:30 (we're staying up north in Princeville). I don't scuba dive, so I'm looking for suggestions on how to spend 4 hours in Poipu. The beaches are beautiful, but if I need to get out of the sun does the Sheraton or another resort of have a shaded patio that that they'd let me relax in and read a book, (and possibly take a bit of a nap)? Also open to suggestions beyond the beach and shopping. Thanks!!
