I have been to Tunisia (Sousse, Hammamet, Monastir and Tunis) a few times and love the place. The local people are quite persistent with their begging but will leave you be if you are firm with them. Don't forget it is a 'third world' country and the average wage is real low. Even if not well off by your own countrys standards, you are like a millionaire to them...they see anyone who can afford a holiday there as extremely rich. Beaches are great, markets (souks) are cheap and if you get a chance..go to the flea(sorry camel) market. Also take an organised trip to the Bedouin feast out in the desert where you will be served national foods (which aint bad) and wine in bottles which arrive balanced on a waiters head. Also visit religious sites and the 'Star Wars' desrt setting. Loads to do there. Have fun. Best wishes, Mike.
PS their second language is French so if you speak it...even better.
