Have a 10 year old and a 12 year old. We have a week in Chatham. Must dos are a whale watch and Pilmouth Plantation. We want time to relax too. It has been suggested we do Pilmouth either on way to or from Boston due to traffic (we're going Saturday to Saturday) but it doesn't seem too far so wonder if doable mid week from Chatham. An hour or so drive for a day trip seems ok to me.
