I asked this question in london forum and then realized I should have asked here.
my family of 4, 2 adults and kids will be 9 and 11 at time, are taking a day trip from king cross area on a Saturday in August. I want to see some Harry Potter sites but have fell in love with Oxford from Inspector Lewis. I want to see some beautiful streets, colleges, and go punting.
Can you all help me figure out things to see and do.
