Hello. Welcome to the forum
Arillas has a beautiful beach and the sea is shallow , Sharon's pool bar and Mirage Pool are always popular on the seafront with visitors, and there is always as much or as little to do as you wish. My grandson, who has been on several occasions to Arillas has always found other children to play with, and I find the nationality ( language ) of the other children is not a problem .
When children play, they play, they always seem to find something in common, I’m sure your daughter will have a wonderful time.
Have a fabulous time in Arillas
