I personally think it's a bit overrated

The tour guide (a Hawaiian teenage girl, very energetic) is super awesome and nice, the safety tour guides also works super hard. It's the tour itself that I gave this rating. The tube would keep spinning and spinning which made me dizzy and created minor headache. I really hope that there is a way to force the tube to alway look forward. Some sort of a "1-person" short floaty canoe or kayak would have made this tour much more enjoyable. Thanks!
