We went on the overnight excursion and yes it did include a trip to a carpet place, but go be honest we found it really interesting and was also a chance to get off the coach for a break. The silk carpets were beautiful, and we were also shown around the looms and told how they got the colours into the wool, we found it very informative and interesting, even though we had been to factories before. Just go with the flow, or stay on the coach, but for us, it made a nice break from the coach. We were also taken to a cotton factory/shop near pammukle which was also good and very cheap.
