I'm staying in London for a summer job and have some time off next week so I'd love to explore more places. My idea is to rent a car on 18/08 in the afternoon/evening to go to Bournebouth. There I'd like to watch the sunset on the beach, maybe having a little swim and walk around the city. The following day I'd like to visit Bath, Stonehenge and  Highclere castle.

 After that either giving the car up back in London or going to Southampton, spending one night there and returning the car on 20/08 midday.
