We're planning to visit Buckinghamshire for a long weekend, Saturday to Tuesday. We're staying in High Wycombe, chosen mostly because it's halfway between us and my brother's family, who will be joining us. All in all, there will be 6 adults and 3 children aged 11 months, 2.5 and 6 years, all girls
I think High Wycombe is fairly central, so we can travel to several places. On our to-do list is the Roald Dahl Story Centre in Great Missenden (the one in Aylesbury is closed until March), and Hughenden as we have NT membership. I wanted to sneak in an afternoon at Bicester, but with three children that might not be a bright idea 
Can anyone more knowledgeable than us please give us inspiration for more stuff to do? The 6 year old is into books and history and loves cathedrals and good museums. The other two girls will tag along, as subsequent children are wont to do!!
