Our family (with 2 kids, 10 yrs and 13 yrs) are traveling to Lausanne for Thanksgiving weekend. My itinerary currently looks like this: Thurs-arrive in Geneva, drive to Lausanne; Fri-drive to Gruyers for chocolate factory tour and maybe cheese factory visit; drive to Montreux for Chateau Chillon and have dinner that evening with friends in Geneva; Sun-visit Chamonix or Annecy.
Questions: is driving better than taking trains? Right now it is a cheaper option, and it's a little easier for our kids. Is it easy to drive to France for the day? Also, is it worth going to Chamonix at this time of year? The lift is closed, so we would just be looking around the town, and possibly hiking a little if it isn't raining. Maybe we should do Annecy and dinner in Geneva on Sat to minimize driving, and save Montreux for Sunday. Any other thoughts?
