That will be absolutely fine Stewind. Enjoy Tunisia, it's a fascinating country.

the only dress code ive ever noticed is some hotels dont like beach wear in the evenings in their restaurants,my partner wore shorts and nice t-shirts or cropped trousers and light weight shirts in the evenings and they seemed to be what the majority of men wore.

In some hotels they insist on men wearing trousers to dinner. Just check with your travel company on the internet as they normally have it written on hotel details.

I came back from the Salem on sunday &, although there is a notice on the diningroom door asking people not to wear shorts/beachwear etc for dinner, very few people seemed to abide by it & it wasn't enforced.
Have a fantastic time, I'm so jealous, wish I was still there !!
