I LOVE Divi's beach. There is sometimes a drop getting into the water but it is usually manageable.
Another favorite of ours is Friar's bay. And you can't beat the Friar's Bay Beach club for lunch.
We went to Pinel once and we were not impressed. The water was never more than waist deep unless we wanted to go into the boat channel.
We enjoyed Anguilla the one time we were there but not enough that we care to get back there.
