Definitely not! I took a tour with Wings Over Kauai and my experience was fantastic. I chose Wings Over Kauai because I felt like I was chartering my own private plane. Wings Over Kauai has a four-seater airplane, so it will only be Captain Bruce and your party (2-3 people). Wings Over Kauai also has the option to customize your tour to allow you to fly over the sites you want to see. I wanted to see all the waterfalls on Kauai and Captain Bruce, the friendliest Captain you will ever fly with, flew us around the entire island and took us, as he jokingly told his wife afterwards, "to every [--] waterfall on the island". If you think that helicopters have a better view than an airplane, think again. The airplane Wings Over Kauai uses is engulfed with windows and I never noticed the wings my entire flight. I guaranteed that a flight with Wings Over Kauai will be a highlight of your trip!
If cost is a concern, it shouldn't be. You should visit an Activity World booth, one is conveniently located at Coconut Coast Market. You will need to attend a timeshare presentation. Timeshare presentations are incredibly lame, but well worth your time. My tour should have been $260, 70 min. for two people, but it was drastically reduced to $96.
