You can knock off the transport there and back from the budget.

Had some wonderful, if blustery, childhood holidays in Brittany, plus 20 years ago I went to Dieppe and Rouen on a school trip. Great bunch o' places. Was a complete mindpiss for a kid going away without his parents for the first time though, especially a massive fight on the ferry back our bus driver broke up and hanging around with the school thugs who thought it was well funny to walk round Rouen Cathedral with a dictaphone repeat playing a recording of "For the fookin' fifth time, what the fook is your name?" :-/
