Our tour was a great success, Roman sites without any tourist, unheard of. Great tour guides and very friendly people.
The only thing I would have changed if I had known was the timing. The holiday caused some slight problems, like a Hotel fully booked (the Novotel in Constantine) and closed restaurants. The holiday celebrations in some establishments took the rest of the week. Also, closed museums & sites. Fortunately, due to the influence of Kader, the tour guide up to Constantine, were we able to see what we were supposed to see. Our thanks to him. We were also very happy with his replacement Omar.
