My friend has just returned from this
hotel and she enjoyed it, she said the food was nice if a little repetetive.
The weather will still be lovely when you go, sun bathing during the day and nights a little cooler, you may need a cardie in the evening, but not every evening. You might even get an odd thunderstorm, but these dont last long and are spectacular to watch.
Local beer (efes) is cheap enough, you will probably get it for around 3 lira and vodka and mixers are around 6-8 lira, depending where you drink. Dont go for the brand names like smirnoff etc, as these are heavily taxed by the Turkish Government so are quite expensive, just stick to local drinks.
Sorry I cant help with the Man U bar.
