just some feedback on heli tours, while we were out with Dolphin Discoveries a young woman and her husband were on the tour, we chatted before we went out and I explained this was our second trip with Dolphin, having done it just a few days prior.
she indicated "wow that is really a good recommendation, to go again same vacation!" what she also said was "I'll tell you what NOT to do even once - don't go on the helicopter trip, over 200 a person, 5 out of the 6 people on one helicopter and all 4 on the other copter threw up the whole time. totally not worth almost $500 bucks a couple." her words, not mine.
I went on a Blue Hawaiian in Maui two years ago, I don't get car sick or boat sick but I was sooooo sick on this helicopter trip I can't even think about it now. I still have the video, I can't even watch it. I would never do it again.
might want to rethink if you get even a little motion sickness.
