We have been to Paris before. Our niece has never traveled anywhere before. We plan on a week outside of Paris (Normandy and Val de Loire) with a rental car and then a week in Paris and staying in a rental flat near rue Montorgueil. We are considerably older than our niece.
We are looking for suggestions that an 18 year old gal would enjoy. She's bright (and wants to see some museums), a bit conservative (I doubt the sewers would appeal), and fairly normal for an American teen. We asked her to list things she wants to do in Paris so we have that list and it is a standard list of most everyone's favorites. I looked for threads on this subject on the Paris forum but they were usually rather vague with few real suggestions.
One item on her list was to the Opera and we will take her on a tour there. We secured tickets for the Friday fashion show at Galeries Lafayette. We'll probably take a Bateaux Mouches cruise on the Seine. Lots of walks to different neighborhoods and perhaps a walking tour or two (we found one that looks like it caters especially to younger people). Since she wants to visit some museums we are thinking about the Paris Museum Pass (but for how many days?). We don't want to overdose her on museums even though she suggested several but with the pass you can return to, for example, the Louvre for short visits and not get overwhelmed on one visit.
So, we are looking for suggestions of things that are likely to appeal to an 18 year old female. Music? Other fashion options? Walks? Shopping? And anything that you suggest.
