Last night I was able to redeem some Alaska FF miles for a 14 day trip that will start in Paris and end in Rome in April 2016. I have a three-day free window after I leave Paris. That as-yet-unchosen city will be followed up by Venice. Easy and inexpensive flights from Paris that are ALSO easy/inexpensive heading into Venice are Budapest and Barcelona. (There are others, I am sure.)
So I am stuck and would appreciate input. Both cities look great. I love Paris, Prague, Dubrovnik and Venice. I was lukewarm about Vienna (confusing to get around for me somehow), didn't much care for Brussels and am not a huge fan of London (too big and too modern).
Also - if I've overlooked the perfect other city solution, I would love new ideas. Thanks!!
