We are a group of 6 friends who are spending a week in Provence in late September. We are hoping to arrange for a guide with a van (to accommodate all 6 of us) to give us an entertaining, insider tour of the hill town region. We will be staying in Antibes and Gordes. All suggestions are appreciated!

While I can't personally recommend this guide, the referenced episode could be helpful to you.
