On Castaway Cay, they offer two packages for rentals. One includes a float, snorkeling equipment and one hour of bike rental. The second includes all of the first package plus the stingray experience. Does anyone know if the second package limits the snorkel gear to the time spent with the stingrays or if you can use them all day? The reason I ask this is that the stingray package alone only includes the snorkel gear for the time you are there (that is you can't take the gear and snorkel in other areas).
