It's great that the Eiffel Tower Observatory ticket is included, so I don't have to go to the website and buy a ticket separately. The guide meets near the Eiffel Tower and walks about 5 minutes to enter the Eiffel Tower together, and continues to explain the Eiffel Tower. There are people of various nationalities, so even though it's an English guide, it's easy to understand. The guide goes up to the 2nd floor, and the rest is a course where you go up to the observatory and look around on your own. More than the explanation, the night view is just beautiful. If you ask the guide anything you're curious about, they'll tell you everything. They are kind.
