Options -
Van to Dogobayazit (Ishak Pasa palace) to Mardin to Ufra - basically drive Mesopotamia
Antalya as base and tour Perge, Aspendos, Side; can do side trip to Kas,
Kas as base and tour Kekova, islands and ??
Sirince as a base - not sure there is enough to do here for 4 to 5 days
Antalya and Sirince split 3 and 2 days - seems overly optimisitic
Welcome any suggestions
