This is definitely an activity you want to wake up early for! The earlier the dive, the calmer the ocean, the more friendly the sharks are! MAKE SURE YOU HAVE DRAMAMINE. Many people on our adventure were sick… don't let it ruin your time!! Even if you don't think you'll get seasick, just take it in case. You can get it at ABC stores, Walmart, Safeway etc. The staff were lovely and really made sure we had a memorable time! Saw about 10 Galapagos sharks which was super cool! We booked the transport up to the north shore with them for peace of mind, but they notified us one day before saying they hadn’t reached minimum numbers and needed to cancel out transport (which they told us could happen booking so is understandable), beware of that! If you are Ubering up to the north shore… good luck! Try grab a business card when you check in for a lovely Uber driver who might be able to take you back to Waikiki.
