Does anyone know if the tour company Popular travel is reputable? My family will be stying in Avignon in mid to late August and it was recommended we book with an organized tour for the trip to Nimes and the Pont du Gard. It is a 10 hour tour that will visit Uzes, Nimes and the Pont du Gard. Please advise if you've had any good or bad experiences with this company. Thanks !!!
