River Ventures rescued our 3-hour manatee swim experience in Crystal River when another company we were booked with had an unexpected issue with their boat. This was arranged for us with only about 24 hours notice. Fortunately that company had a good relationship with River Ventures and had asked them to ensure we were not let down so really we feel we can strongly recommend both companies for ensuring that we had the amazing experience we had been so looking forward to. River Ventures accommodated us without compromise, we had excellent service from start to finish - being welcomed at the centre, educated prior to the boat trip and swim, provided with all our needs (including hot chocolate on the boat), the fabulous boat and our swim with the manatees, photos taken for us (without any pressure to buy) and the lovely gift shop. Our captain and guide were both fun and sociable, and committed to finding the manatees for us to swim with (despite this being an August afternoon, we were not disappointed.) They were great with the kids too and we all learned a lot from the knowledge that they shared. This is a must do experience and for us it was the most memorable day of our trip to Florida which had included Miami, the Keys, the east coast and Orlando. Thank you RV! We can't wait to come back some day.
