Geneva and Lausanne work but are much more than 4 hours away from Venice.

I appreciate all the advice.
We basically arrive in Paris on 12/31 and leave on 1/3. We basically have until 1/7 to get to london ( we are flying from venice -so I don't want to over do it but Being that my boyfriend and I have both been to paris and venice- we wanted to go somewhere we both hadn't been to.... So what I'm hearing from everyone is Interlaken stresa, lago maggiore, luasanne, geneva- for an overnight stay which would work? or is are three cities too much?

Hi dom,

Do you already have your flight from Venice to London paid for?

If not, I suggest visiting Dijon or Beaune or Lyon or Reims for a few days before returning to Paris and going to London from there.

PS,

Left out Strasbourg.
