I just had the opportunity to see some of the photos of my parents trip with you. It looked amazing and brought back some memories for me as my wife and i explored the Luberon/Provence in 2005 and I believe I saw some of the same villages and cities (Gordes, Roussillon, Avignon, etc).
I want to thank you for the amazing trip and care you showed them and Marilyn and Jay. My mom keeps saying she would go back in a second!
I promise, if we are back in your area, we will let you know. And please let me know when you come to the states.
