I would check the International Herald Tribune's site: http://www.iht.com

It has an excellent travel section. Too, one can subscribe to its weekly travel alert newsletter. Plus, you can email the travel editor with questions about travel. It seems to me that your question would be one that would generate a comprehensive response from them.

I enjoy reading Patricia Wells' restaurant reviews there and am about to enjoy a restaurant in Venice in a couple of weeks about which she has raved.
