We fly to Paris on Monday. Our current plan is 4 nights Paris, 1 night Strasbourg, and 4 nights Switzerland (Jungfrau region only). Given the current weather forecast for Paris next week, I am not sure I can handle the heat in Paris, even with a hotel with AC. Touring during the day sounds miserable.
Two thoughts- switch weeks and do Switzerland first. This assumes I can find new accommodations. I am willing to consider two areas, perhaps Splitting the nights between the Jungfrau region and Luzern. Paris won’t be a problem finding a hotel week 2 (starting 7/28 or 7/29). One member of our party is leaving after 5 nights and joining another group. She needs to end up in Strasbourg that day.
Other plan: skip Paris almost completely and just focus on Switzerland. Buy the 8 day Swiss Pass, and make full use of it, and enjoy a more leisurely trip through Switzerland, adding additional areas, preferably ones on the cooler side. The person who is leaving early can have a 4 or 6 day pass.
If I decide on plan 2, what other areas would you recommend? What would be good for 4-5 nights outside the Jungfrau region that would be relatively easy to find last minute accommodation?
