I will be staying right off Waikiki beach at the aqua palms and spa hotel. I will be there for about 4 days or so (Sunday - Wed.) I would love to dive (I have my dive license), but I don't know the expense and if I could just rent and shore dive. Someone please help me out rental shops, best places to dive to see marine life, and prices, etc. I'm leaving this Sat (March 13). Thanks!
