Disappointed

This was a waste of time and money. Apparently the moon has a lot to do with the “lights”. There needs to be movement in the water to even see the lights. Not sure what I expected but I was disappointed!

Beautiful bio bay!

The bio bay was so fantastic! I highly recommend seeing it. We went with a pretty full moon and still had a ton of visibility.

Magical experience

The experience itself did feel short, but I would have stayed in the bay for hours if I could. We were part of a bigger tour group that got split onto 2 boats, a smaller boat and a bigger boat. We got onto the smaller boat, and thankfully it worked out that way, because our tour guide told us the group on the bigger boat would not be able to swim in the bay. We would have been VERY disappointed if that was the case for us, but it wasn’t. We traveled with a 9 y.o., a 7 y.o., and a 3 y.o., they all went in the bay and LOVED the experience. We brought our own swimmies because the younger 2 did not do well with life jackets provided on other excursions. I definitely would recommend this excursion and would do it again if I could. We Loved it!
