I am sure that single supplements are still widely available Ray. I used to holiday two or three times a year with a friend but never liked sharing a room so always booked two rooms and paid the extra charge. I was never refused anywhere, one of my favourite websites was Flights and Packages, we used them several times and booked two separate rooms every time. We had some great holidays, went on two Nile cruises as well as gulet cruises and booked separate cabins every time. I now live in Çalış so haven't been on holiday lately, my friend comes here to stay instead. Good luck with your search
