I went a few years ago, stayed at the Sahara Beach Hotel just outside of Monistir [sp] I found Tunisia OK, people friendly, polite, but can be very pushy in the markets etc, wont leave you alone to browse, and you have to haggle over every thing, can be fun but some found it daunting and a bit intimidating.
Went to a Beduin feast as an excursion, again enjoyable, but every one there was out to get some money from you....
Goods were cheap, and its worth going off the beaten track to have a nose around, leather jackets can be got very cheaply from villages just out of Monistir..
Was it good enough to make me go back?? Not really, but would not say I would never go back...
