Arrondissements to stay: the 7th is where the Eiffel Tower is located. I’d recommend exploring Rue Cler market street (7th). the 8th is where the Arc De Triomphe, Champs-Elysees The 1st is the heart of Paris where the Luvre and Jardin des Tuileries Attractions/things to do: You can book on Expedia, GetYourGuide or Viator The Luvre Musee d’orsay Walking food tour (Montmartre) Cooking class Shopping - if you’re interested in high end luxury stores you’ll need an appointment Seine Dinner Cruise (at night) Go see Notre-Dame Eat as many pastries as you can If you want to leave the city you can to day trip to Normandy, Versailles, Champagne, Mont Saint-Michel
Spend time in old town. It has a lot of night life. If you want to enjoy wine tasting (what Bordeaux is known for :) )- you must book a tour in advance (at least 2 months). Wineries are generally not open without reservations or outside of wine tour. Expedia, GetYourGuide or Viator have options.
There are so many things to do around the venue. Take a peak at the website!
