Hi Fabio,
Thank you very much for your feedback and we are glad to hear that you enjoyed the tour and tour guide Michel. We are very sorry to hear that you felt 2hrs was not enough time at Stonehenge, as some customers came back earlier and felt there was too much time. We try our best to arrange the itinerary in such a way as to satisfy all of our customers and will look to change this in future based on feedback from customers such as yourself. Regarding the microphone, Michel says he asked everyone if they could hear him and had a positive response. If you had mentioned on the day that you were struggling to hear, then he would've adjusted the volume accordingly, so I'm very sorry that you missed some of the commentary and that there is nothing we can do to correct this now. We will continue working towards providing an excellent, 5-star experience for all of our customers and are appreciative of your valuable feedback.
