I really enjoyed Hawaii, but that was for my Honeymoon, so it wasn't specifically for diving, but since Hubby and I are both certified, we had to do some diving, we dove 3 days (two tank dives, mostly drift dives) and we agree it was probably one of the main highlights of the trip, would love to go back to Hawaii for some more diving in the future, but that can get expensive fast. (The cost for diving wasn't too bad, i think around $80 per two tank dive, including rental gear - pretty reasonable, and the rental gear was the same BC we have at home, so we lucked out lol, we didn't bring any gear with us that trip - again since it wasn't a 'dive trip'). We haven't really done any major dive trips yet. Been content with Florida diving
