That seems like a pretty good itinerary to me, it would be a pretty relaxed trip for most of it (by this communities standards anyway).
If you wanted to tighten the schedule a little I think the time in and around Tunis and Sousse could probably be trimmed a little, but otherwise I think it looks good.
3 days in Tunis
allows you to see everything at a very relaxed pace. This will help get a feel for the medina
, but it isn't to the same standard as Morocco's (probably the closest equivilent is Rabat) and on the third day you may start to get a little bored. (We stayed 3 nights, but that included a daytrip to Dougga, but we had an extra night at the end for logistical reason to fly home)
If you wanted to just do the the bare minimum I think you could cut this to 1.5 days. A half day each for the Medina, Bardo and Carthage, transist between them all is quick and straight forward.
The tradditional addition to a visit to Carthage
is the village of Sidi Bou Said
, which is a nice place to have a meal and a glass of Muscat de Kelibia overlooking the Mediterranean.
A car to pick up Ichkeul, Dougga and Kerkuane feels like a good idea.
I didn't realise how short the drive is to Ichkeul
from Tunis, depending on how much time you wanted to spend at the lake, you could probably combine with the drive to/ visit to Dougga
, and stay nearer the ruins rather than returning to Tunis. Though you may well get more out of the National Park than I would. (Don't forget Dougga has a tenative site as well Numidian Mausoleums
though this would barely add 15 minutes to the visit).
I think we did your Sousse
itinerary in 2.5 day/ 2 nights, and managed to visit Monastir
's Rabat as well (recommended). Sousse is a nice medina, though it felt the most touristy site in the country. And whilst it is nice, there isn't much to see beyond a half day's exploration (plus wandering around for ambiance in the evenings after side trips). Kairouan
is an easy day trip and El Jem
can be picked up on the way to/from somewhere farther south.
On the way south I think Sfax
is worth a stop, it is a TWHS and from memory was the least touristy medina we visited, probably not worth an overnight stay unless it eases the itinerary. Likewise for the Oasis at Gabes
, the town will probably feature logistically anyway if heading to the desert, I missed the oasis though, so can't say if it is a worthy stop.
I enjoyed Matmata
, though I fear it may perhaps be a little underwhelming, unless you are a big Star Wars fan, or stay the night in a cave. But adding Tatatouine
should certianly improve the visit.
I have no experince of Djerba
, but flying back from there makes sense, and can probably provide a nice place to relax.
I would also be interested on how much Harissa
you put on your bread on the first day vs last day of the trip.
