Self-driving around the British island D3: London Eye-Westminster Abbey-Royal Observatory Greenwich.

After purchasing the City Pass, you can take the double-decker sightseeing bus and Uber water cruise on the Thames River by land and water. 9:30 9 3/4 Platform 10:00 Double-decker sightseeing bus 10:30 South Bank Center 11:00 London Eye 13:50 Westminster Abbey-Big Ben 15:00 Uber Boat-Ancient Ship-Royal Observatory Greenwich 17:00 Buckingham Palace Tip: Next to St. Pancras Station is King's Cross Railway Station. There are many British people queuing to check in at Harry Potter Platform 9 3/4. It seems that the fan economy is also internationally accepted, and the souvenir shops are also crowded. The Royal Observatory in Greenwich is relatively far away, so you can enjoy a tour on both sides of the Thames by taking an Uber cruise.
