it depends on the time if it will be day or night if it s after 10:20 it will be so hard to find some thing you have no options the only way is getting a kind of privit car who drive between towns and believe is not safe to go in one of them that time bcs of some drunk ppl who will be in the same car if you can have a deal to get the all car for you it will be better.
And the safier way to go is to get a touristic car from the airport who is really expencive like 180 dinars.
If is in the day i recommend that you use train it s the most safe and sheep in tunisia.
I use A2B Transfers www.a2btransfers.com. The are not as cheap as medhotels but they take you directly to where you are staying, which if it is an appartment saves taxi costs. We have been taken to the airport in a 4x4, a really swish Peugeut and also in a normal small tourist bus. It costs Â£17.50 (roughly) for two people one way but I find it is well worth it.
Last year I took medhotels several times (8 euro singel way) to Riad Palms, but I didnÂ´t stay at the hotel due to my privat appartment nearby in the area. The drivers has always been on time and meet me in the arrival at the airport with the sign "Medhotels" in front of them.
I have also booked arrival from Monastir to Sousse/Riad Palms and with the return to Tunis/Carthage, and by email medhotels asked if this was correct, I confirmed it was and got no further questions about it.
Medhotels use local companies and it hasnÂ´t been a problem on the arrival if you would like to stop between the hotels that Med has.
I haven't used the forum for a while though just wanted to say i'm going to tunisia today for 2 weeks.
Also i know some others are going today and this week so i wish that everyone has a nice time, and that the weather stays sunny! lol
