My daughter and I will be in Aix in Provence in mid-July and are looking for a day tour to Cassis and the Luberon villages. "Discover Provence" has wonderful reviews on this forum and what looks to be a fantastic tour to the villages, vineyard, etc. However, we recently found a tour company by the name of "Provence-Xplorer," which offers a tour that includes Cassis and the Luberon villages in the same day. I haven't found any reviews on Provence-Xplorer that departs from Aix en Provence. Are any of you familiar with this tour and the quality? I sure would appreciate some input! Thanks.
