Hello everyone, Just to double check it is Bus Nr 12x or 13x that serve the National Park from Brighton, is that right? Do you think we could make use of a day pass and just hop on and off the bus from Cuckmere Inn onwards to Birling Gap or do we have to buy singe tickets instead? We just plan a day trip to/from Brighton so would go back at the end of the day. Do you know what a day pass would cost between these places? Thank you.
