We are planning to make a trip to Zurich and Paris from Seattle. We would like to fly from Seattle to Zurich and spend 3 nights then drive or take a train to Paris. We would like to spend rest of the nights in Paris and fly back to Seattle. I'm having a hard time finding out the best way to create a vacation package like this. Are there any good websites that offers multi-city booking with hotels? Priceline and Expedia doesn't offer customized packages that has 3 nights at one place and 3 at another. Any advice will be appreciated.
