Hello! That sounds like an amazing trip to Tunisia. Here are some travel tips for your journey.

Best Time to Visit:
The best time to visit the seaside towns of Hammamet, Sousse, and Mahdia in Tunisia is from late spring (April to June) to early autumn (September to November). These months have comfortable temperatures for beach activities and sightseeing.

Route and Accessibility:
You can reach Tunisia via Tunis-Carthage International Airport, which is well connected with many cities worldwide. To reach Hammamet from the airport, you can take a pre-booked taxi or a bus. For intra-city travel in Tunisia, consider options like local buses, Louages (shared taxis), or even renting a car.

Accommodation and Booking:
Hammamet, Sousse, and Mahdia offer a wide range of accommodations from luxury resorts to budget hotels. Booking.com and Airbnb are well-used platforms for booking accommodation. It’s recommended to book in advance especially during the peak travel seasons.

Clothing and Essentials:
Pack lightweight and breathable clothing for the Tunisian climate. Swimwear is a must for beach activities. Sunscreen, hats, and sunglasses are important to protect yourself from the sun. Don't forget to pack an adaptor for your electronics.

Health and Safety:
Standard travel health precautions apply. Make sure your routine immunizations are up to date, drink bottled water, and be aware of what you eat. As Tunisia does have occasional safety issues, it's good to stay informed about the local situation and follow the advice of local authorities and your travel advisory's advice.

Local Etiquette and Respect:
Tunisians are quite relaxed, but it's important to respect their customs. In public places, dress modestly, especially during the holy month of Ramadan. Remember to ask for permission before photographing locals.
