I must admit we book some of our holiday in a A I, mainly down to cost the all inclusive deals that are around, we still do go out for a few meals but not every night probably about 50/50, and usually go back to the hotel for a a few drinks in the evening as its the cost of alcohol that makes Turkey expensive. If your out every night it mounts up we had a shock a few years ago when we worked out how much we spent in 16 days in Dalyan staying bed and breakfast.
That said if there were not AI hotels we would still go to Olu Deniz just as we still go to Dalyan where there are no AI hotels, chances are though we may not go as regularly as we do now.
We have usually booked our October week by now but are holding off as the amount of last minute deals around are amazing , we have already seen the flights we have for may are less than half what we paid a few months ago. One travel agent had a week in Oludeniz for £98 including flights last weekend for this week.
