We paid 60TL per adult and this included food and drink available all day (all fast food so not the best you'll have in Turkey).
Some of the rides were closed at times throughout the day but they all opened at some point. It was really quiet so we never had to wait more than 1 minute to go on...
Kids love this park too much but my kids teeth broke in the kids pool; generally it is good to have fun.
The cost per person is 60 euros for adults which is too high but I used it during my stay in club yali.
