Is it worth going to the top of the Eiffel Tower?

Not really. The best view of Paris includes the Eiffel Tower, so go to the Montparnasse Tower or the top of the Arc de Triomphe instead.

Should I speak French?

Always start with 'Bonjour' before asking a question in English. It is considered rude not to acknowledge the shopkeeper or waiter first.

How to plan a romantic weekend in Paris

Focus on one or two neighborhoods like Le Marais or Saint-Germain-des-Prés to minimize transit time. Book your dinner reservations and museum time slots exactly 30 days in advance to avoid long queues that kill the mood.

Pick a single base. Don't try to cross the city. Stay in the 4th, 6th, or 7th arrondissement. You can walk to most romantic spots, which is better than being stuck in a taxi.
Secure your reservations early. If you want a view or a specific bistro, use an app like TheFork or the restaurant's website 4 weeks out. If you walk into a popular place without one, you'll wait outside in the cold.
Build in 'flâner' time. The most romantic moments in Paris happen when you have no destination. Leave at least 3 hours each afternoon to simply walk along the Seine or through a park like Jardin du Luxembourg.
Pre-book major landmarks. Never wait in the ticket line at the Louvre or Eiffel Tower. Buy 'skip-the-line' tickets online at least 3 weeks before you arrive.
