I have a conference in Boston in late October, which runs on Thurs and Fri. Was planning on staying in Boston Wed night thru Sun, but now entertaining the idea of going away for maybe Fri and Sat nights or maybe just Sat. Could rent a car if necessary. Any ideas where we could eat at good restaurants (and recs please!) and see some sort of charming seaside town, albeit off-season? Been researching Provincetown, which appears to be ferry accessible from Boston? Or go further down cape?
