The experience was pretty cool but could have been great. You hop on this little underwater motorcycle with a dome of air over your head and cruise around a reef in a guided tour.
The registration process was sloppy forcing everybody to re-fill out all the documentation that we had to fill out on the ship before receiving our tickets.
The staff at the excursion were great, friendly, engaging and a lot of fun but the equipment was really worn. My wife's undersea vehicle was only capable of spinning in circles which left her upset and disoriented and way at the back of the group away from everybody. Once they realized the issue the scuba divers that guide you had to grab onto her sub and guide it manually through the rest of the tour, but she missed the "fun" of it and was not offered the chance to go again with the second half of our group on a working sub, which was a bummer.
Probably the best food of the entire cruise, not counting the dining room on night one. I wish the normal buffets onboard had had cuisine as tasty and with as much variety, style and flavor as what they served on NCL's island.
