London

Here's an ideal itinerary for 3 days in London, keeping in mind the senior citizens' needs:

Day 1:

• Start the day with a hearty breakfast at a local cafe or restaurant. I recommend trying out the traditional English breakfast, which includes eggs, bacon, sausages, baked beans, grilled tomatoes, and toast.
• Head to the British Museum, which is free to enter and has a vast collection of artifacts from around the world. The museum is wheelchair accessible and has elevators for those who need them.
• After exploring the museum, take a leisurely stroll through the nearby Bloomsbury neighborhood, which is known for its beautiful Georgian architecture and charming cafes.
• For lunch, stop at a local pub or restaurant for some classic British fare, such as fish and chips or shepherd's pie.
• In the afternoon, take a guided tour of the Houses of Parliament and Big Ben. The tour is wheelchair accessible and has audio guides available for those who need them.
• End the day with a relaxing dinner at a local restaurant or pub.

Day 2:

• Start the day with a visit to the Tower of London, which is wheelchair accessible and has elevators for those who need them. The tower has a fascinating history and is home to the Crown Jewels.
