Great time! - Sugar Sugar Bear and his crew were very helpful and funny. They really made the evening enjoyable! Really enjoyed the experience! Take bug spray. We got eaten alive at starfish point, but it was really cool seeing the starfish. As for the bioluminescence, make sure you go on a new moon to really see the bioluminecence at its best.

Don't waste your money. - We were very disappointed. If you think you might see what is depicted even a little bit while on the excursion... You will be very disappointed. Plus, they don't tell you that the whole area is infested with mosquitoes. This is the biggest waste of money. Look at the photos instead of spending over $150 and getting bombarded with mosquito bites.
