The picnic they were doing was still within the city of London. Where else were they going? There are many places in several corners of the city that they could take advantage of instead of traveling out of town, which would take time to get there. Not to mention the return trip, which also required a lot of time and energy. The best option was to visit a park in central London.
Hyde Park. That's the name. A large garden to pamper the weekend with views that could refresh their eyes and minds. People could do various activities there, such as walking, jogging, cycling, and even renting a boat for those who wanted to enjoy the lake located inside the park. But, at the time, Elle would only choose the first activity, which was walking. She was not interested in other activities. At least, for the moment. Whether if Lucas asked her to do other things, her mind might change.
