This is my son's favorite thing to do.  He loves to play with the sand and water for hours.  I love the umbrella because it keeps him from baking in the sun.  The only thing we don't like about it is that the bridges keep falling down every time he runs a car over them.  Step 2 needs to rethink the design of the bridges so that they snap in place.  Other than that minor annoyance, it's a great toy and I've recommended it to my friends.
