In your backyard??? Legal or illegal???
My DH would say, "what docs?" I fully expect him to ask me on the way to the airport . . . "Now, where are we going again?" I'm not kidding. He always leaves all the planning up to me and just comes along for the ride. He knows we're on the Disney Med cruise and flying to Barcelona, but thats about it. Probably a good thing. If we were both type A, there would be big trouble.
My DD (7) told me tonight that she has a sore throat.

I told her that NO, shes not allowed to get sick during the last week of school and only a week before we leave for Spain!!!
John, check out the cruise critic sight under destinations. There is a little bit of info there on beaches. I think Olbia would be a good destination to rent a car. I wonder if there is a car rental agency at the port. If not, its probably too much of a hassle for just 1 day.
