@KindergartenKop , yes a lot also apply to Tiffin and other top schools you have listed plus RGS. Yes in my ds's first class the boys came from Worcester Park, Leatherhead and Windsor as well as the local areas. There are lots from Chiswick, Sheen, Richmond, Twick and then Weybridge, Esher, wimbledon across the year. The Windsor journey is actually quick and easier than the buses that cross the river at hampton court.
Have you got a favourite if you get KGS/Hampton/Tiffin or are you concentrating on getting through each week?
