I'll be in Oahu from Aug. 15-25. I was going with two friends who don't dive and was just going to take a couple of dive trips. They both flaked on me so I would like to take AOW and then do like 4-5 days of two tank boat dives, maybe some shore dives. Any recommendations for a good boat/instructor. I am staying at HI Waikiki Beachcomber if that makes any difference.
