Thanks, chaps, but the boys are very light aircraft friendly and two or three hours a day in an aircraft as compared to 8 or 10 in car is no comparison. They can do Disney and Sea World etc, but young children are not quite as simplistic as not to like some of the stuff grown-ups like as well.
Leasing would be a good option if one could find someone to lease an aircraft like that.
Norfolk Newbie, if it is just the two of you hire a 172. That's easy enough. A 206 or, especially, a 185, is a different matter.
