I will visit Royal Albert Hall Concert and booked one night for 100 Queen Gardens Hotel. Next morning I will move to the Montegue Gardens Hotel and than I want to visit the Royal Observatory in Greenwich. You know, I don‘t like to travel by Central, Elizabeth…Line. Google show me Bus 55 and moving to train Thameslink (Rainham to Maze Hill).
Question
Thameslink - do I need to buy tickets or is it possible to tap with creditcard?
