The direct route Reading to KT7/8 centres on Virginia Water. Slightly north would be Old Windsor and there's the Toby Carvery for an all-you-can-eat breakfast, or the Windsor Farm Cafe on the Royal estate. Tony, I know that is slightly selfish from my perspective but if memory serves me right, I'd have confidence you are more mobile that the rest of us . .
Last 2 weekends in August / early Sept suit me too
