I just returned from our July 4th cruise on the Pride of Aloha. All of our excursions went off without a problem, even the ones I booked on my own. The ziplining adventure on Kauai was fabulous (I booked through Kauai BackCountry Adventures and saved around $50.00 each). I would highly recommend this one. We went ATV'ing on Kipu Ranch and this was also a lot of fun. We hiked the 6 miles on the lava fields. This was strenous but worth the work as we actually saw lava right under our feet, and my zoom camera was able to pick up the lava going right into the ocean. Extraordinary view. I also enjoyed the Maui downhill bicycle adventure (38 miles down Mt. Haleakala) but make sure you take a jacket as we about froze for the first 45 minutes or so. I would recommend that you do as many excursions on your own as possible as NCL charges quite a bit more for the very same excursion. I used Google and was able to find the companies directly. Happy cruising.
