My grand daughter was terrified, too. She climbed up to the top of my head and hung on like a baby monkey... LOL. She was much happier in the boat, and she still enjoyed the trip and the other snokeling spot. But NOW she wants papaw to take her again, she thinks she'll pet the stingrays this time.
Most people who were apprehensive found that after getting in the water with the rays, they were amazed and awed, and so glad they did. Last night, we booked our second time with Capt. marvins to do it and the barrier reef snorkel. If you don't get off the boat with the sting rays, you'll still enjoy seeing them in the water from the boat, and the great crystal blue waters, and the other snorkeling spots. IMHO the boat ride was worth the 30 some dollars (20 something for the kids) we spent pp for the trip.
