Accommodation and Booking:
There is a range of accommodations from luxury hotels to more budget-friendly options. It's advisable to book your accommodation in advance, especially in the peak tourist seasons.

Clothing and Essentials:
It's hot in Tunisia, so lightweight and light-colored clothing is advisable. Don't forget a hat, sunglasses, and sunscreen. However, dress modestly while visiting religious sites.
