Hi, we are travelling to Europe with our two kids in June, and our flight from the US gets in to Zurich on 16th morning, and we were planning to be in Paris on the 18th night. I was thinking of spending one day in Lucerne and one in Interlaken/Grindenwald, and then taking the train from Bern (or Geneva) to Paris. Is this a good itinerary? Do we have time to go to Zermatt or Geneva? Also, does anyone have good suggestions for hotels for 4 people? Thanks for your help.
