My mom and I had a wonderful outing to South Downs and Seven Sisters with Lawrence! He took us to all the best spots for photos and viewing points. We would strongly recommend you take this tour, rather than trying to go by public transport. We were a little late on the arrival back to Brighton (and ended up missing an inside viewing of the Royal Pavilion), but it was only because he wanted to accommodate another customer's request to stop by a church the customer's parents got married. I wish we could have it made it back on time, but I wasn't too upset given that he was trying to be kind to another customer.
