Are you heading to Grand Cayman with your children? It is a wonderful family vacation destination spot and while you could easily spend all of your time on the beach you don't want to miss out on the Turtle Farm. (http://www.boatswainsbeach.ky/)
Connor was so excited to be able to pet the turtles, we learned that turtles like to have their necks stroked. There is also a snorkeling pool where you can see the turtles up close and another pool with out animals. and an aviary where you can feed the birds. There is also a restaurant and shops. For the older than toddler group, there is an educational centre where you can learn everything about turtles.
It's a wonderful place and I highly recommend a visit.
