Somebody give the 'guide' a script! How many times can you ask people "Hey - do you like the bioluminescence? It's called phytoplankton."??
CONS: I think there were three 'guides' with us on the late night bioluminescence tour. Two didn't speak; they hovered on the outskirts of the group. The third rambled about restaurants, some long-ago bobcat sighting, and who knows what, then would shoot off in a direction without notice (since his single kayak was faster than our tandem boats). One person asked the other 'guide' what the body of water was called; he said he didn't know. Their website says they will leave without you if you arrive late, but they accepted a large late group and went through the legal spiel of 'here's how to paddle' demo a second time, while the rest of us got eaten by bugs (wear pants, Deet isn't enough!). You figure that out when the employee is wearing a hat with full face netting. The "tour" was basically wandering aimlessly in the dark with a bunch of strangers in boats with no directions, no narration. Clear bottom added little to the experience. There were at least two other companies working off this same launch area; sounded like they had more narration.
PROS: Launch area was easy to find. They held everyone's phones in the truck so they didn't get lost/wet. Yes, the water glowed when you disturbed it and that was cool, but that was about the extent of the excitement. No worries with kids - the water is very shallow and life vests are provided.
