Not been there, but it was one on our shortlist (we've gone for a new one opening in Paphos, Cyprus) for Sept. I think you'll be OK, there are lots of reviews by people with families. I'm sure you'll find some quieter places for the evening, that's if you want to get off the hotel resort.
You tend to get the 18-30 crowd stopping in cheaper self catering places than AI resorts.
Have a fab time. I've only been to Crete (of the greek islands) but really liked it, esp the yummy greek food.
