Paris in 3 Days: A Practical Itinerary
Three days is enough for the major Paris landmarks without over-scheduling every hour.
Day 1: Eiffel Tower & Seine
A morning Eiffel Tower slot, then an afternoon at a relaxed pace along the Seine, leaves room to actually enjoy the view rather than rush to the next booking.
Day 2: The Louvre
A guided small-group tour in the morning covers the highlights efficiently; the museum is large enough that trying to add another major booking the same day usually backfires.
Day 3: Versailles
This is a genuine full-day commitment (8-9 hours including transport) — don't plan anything else major around it.
The practical lesson
Versailles alone justifies its own day; resist stacking a second major booking on top of it.
