Laodicea is the ancient stop most often added to a Pamukkale and Hierapolis day. The site is wide, so a drop-off and pickup at the same gate keeps the group together. A chauffeur ties those two times to your plan.
Who it suits
Families and small hotel parties fit a 9+1 Vito or Transporter. Add a guide and a photo team and a Sprinter is the better cabin. In summer a water stop belongs in the note.
You can also go straight from the airport, leave the luggage in the vehicle, and reach the hotel afterwards. Write the stop order when you book.
