We also have a non-swimmer in our group for our Nov. visit and i am not concerned as there are alot of areas he can touch and we will have life vests as well....below is the details DC provided me with when i enquired:
Even for non-swimmers, Discovery Cove has plenty to offer. Not only can you relax on the white sand beaches or one of our many hammocks, but we have an Aviary full of exotic birds to hand feed. More importantly, however, we do provide life jackets so you can enjoy the waterways as well. The devices are designed to keep you afloat, so you would still be able to snorkel with the fish in the coral reef or take a journey down our Tropical River. The lifejackets can even be worn in the dolphin lagoons!
I have included a water depth chart for your review.
