Not sure if it is appropriate, I can ask this here.

This August, I am looking for a 2 night romantic escape with my wife somewhere in Europe.
I have 2 free night rewards, I could pay cash or points for a 3rd night, but I would prefer to keep it 2 nights.
Anywhere in Europe but Spain. Preferably somewhere close to an airport with direct Alicante flights. (I can rent a car too)

My wife likes to drink, so I would not go to cities with bad/expensive alcohol. We prefer to relax or walk a city rather than spending the day queuing in museums.
We have already been to Budapest, Paris, Rome and Vienna, so I would not consider these cities.

Any recommendations? Thank you!
