23 day itinerary review/help - France/Switzerland

I have never bothered staying at the airport when I am leaving from Paris.. unless flight is like 7 am , I do not see the point of spending my last evening in France at a soulless airport hotel. Just get up and take a taxi to airport in am.. unless of course you have such an early flight.. I try and book flights that leave after 9 or 10

Perhaps a night in each of Annecy and Lausanne instead of a Geneva stay.

Whether the short stays will work for you depends on how quickly your family can be up, packed, and ready to move. Remember that you can only go as fast as the slowest person.

I just plotted your basic route on google maps. It's 3,000 km in 18 days, not counting day trips. That's a lot of time from kids (and adults) to be strapped into a car.

Use viamichelin.com to estimate driving times. Remember that they are usually optimal times, you need to add for traffic, pit stops, etc. You can set it for the fast toll roads or the more scenic slower roads.

If possible you should fly home from Zurich. Trains run from Luzern directly to the Zurich airport every 30 minutes and take less than an hour. It seems a lot more convenient than somehow going from Luzern to Paris for just one night before flying home.

One more suggestion -- I find Geneva pretty dull in comparison to towns nearby on Lake Geneva. Unless you have something specific thing to do in Geneva, I'd consider staying in Vevey, Lausanne, or Montreux. The awesome Chateau Chillon is near Montreux.

Although, in defense of Geneva I'd really like to pay another visit to take a tour of the CERN facility.
