Most of the suggestions made above would at little cost - well relative to the money being spent on the prom between Fethiye and Calis - and would meet the requirements of regular and new visitors. How to make it happen, Bar and Restaurants owners to lobby hard for these changes, but unfortunately it will not happen, as too many of them are more concerned with customer numbers and trade of their neighbour /competitor bars, than improving the things that would generate more for the area, and bring in more trade for all.
Take it from me it is the only way to make it happen, and I know from experience of running a seafront bar and restaurant, and being a proud member of the Brighton Seafront Traders Association who did such great work withe Council /Goverment and the big corporations who operate in the area, to make improvements.
