Here's one reviewer's suggestion of popular (romantic) vacation spots in Italy
Romantic Getaways in Italy

Venice (I've heard a lot of complaints about La Serenissima: high prices, too many tourist traps, food is overrated, not so clean)

Italian Riviera seems beautiful - but seems like it's just a more crowded/chi-chi version of San Diego

Amalfi coast/Positano - Gaylon, do you have photos & videos to share?

Lake Como - gotta go visit GC's palazzo

Sicily - will go on a later trip to Italy

Gulf of Poets sounds terrific - anyone been?

Tuscany & Chianti Wine Region - agriturismo & vino

Verona - to the North

Perugia/Umbria - sounds very promising - especially in October during the Chocolate Festival

Firenze/Toscano - also very promising. How is the weather in the autumn?

Staying in a castle - live like Maria or Gaylon - in a really palacial home.
