Hi, my family are due to go away to Tunisia at the end of May/beginning of June. We understand that if you tip in hotels you get better treatment!! What is acceptable and really appreciated? What do you tip the porter and bar staff etc etc. I know it is not necessary to tip but just curious on what would be appreciated. Also is it better to tip in English money? We are staying at the Sovivia Resort in Port El Kantaoui. Thanks in advance
