Surprising - Surprising The weather wasn’t perfect, and the water wasn’t as bright as in the pictures, but it was still an amazing experience! The guides made sure we understood how the bioluminescence works and why it can vary. Even with less glow, it was fascinating to see and swim in. Plus, Starfish Point was a great stop along the way. I would definitely do this again!

Disappointed By Experience - I thought that the actual experience did not match the images on the web site. This combined with the high price per person makes me not suggest this to others. We were surrounded by houses with their lights on which degraded the experience.

No show - Never got the message to meet a full 45 minutes prior to the scheduled time. Was promised an email for an update and I never got one. Actual contact from the tour company looked like a spam text, made no sense and did not match the trip. There was a warning when opening the text. Will expect a full refund or i will not fund thsi
