At first, Noah was not too sure about the sand or the water and clung to us with a little death grip. After a few trips down to the water to refill his water bucket, he discovered that it wasn't all that bad, and the water was actually quite warm.
We had a little picnic and then headed home, where we all took a nice nap. While I would not say that Noah now loves the sand and water (he tried to leave several times, telling us "Bye!" and heading for the gate), it was a nice introduction. I am sure he will soon be begging us to stay longer.
