This was a great experience! I was a little worried going into the ocean at night, but seeing the manta rays made those worries disappear. It was an amazing sight to see! The boat ride to/from the site took about 20 minutes each way and was a little bumpy. We could spend however long we liked in the water. My kids (ages 5, 9, and 12) were getting cold so we only lasted about 20 minutes. The hot shower once back on the boat felt great and the snacks were much appreciated. The tour guides were kind and helpful. I would definitely recommend this tour!
