My trip went very well.  My driver and guide did a great job: always punctual, knowledgeable, professional, and friendly.  I really enjoyed my trip to ancient Carthage.  The Antonine Baths were amazing.  Also, it was fascinating to visit the old military port and the massive cisterns used to store water from the Roman aqueduct.  And of course, the Bardo Museum was very impressive.   I thought the day trip to Dougga was definitely worth it:  it had some of the most impressive ancient ruins concentrated in one spot that I have seen.  All in all, a great trip!
