@frillseeking We were in Sani Club.
It wasn't awful, and friends of ours really enjoy it and go back every year.
We visited out of school holidays and I just found it a bit busy and a bit boring, and quite pricey.
The beach was so busy that you were basically all sitting in lines with 6 inches between sunbed groups. The baby pool was v busy and noisy. The edge of the baby pool was incredibly slippery and my DC fell over a few times on it.
We've also done Domes of Elounda which was equally enjoyable to Sani although the rooms weren't quite as nice and the terrain v hilly.
Personally I'd rather spend less money and go somewhere I'd enjoy more, and then pay extra for childcare when there. We went to the Middle East (not Dubai) this year and had a fabulous time. Lovely resort, amazing food, just a few more hours flying than Greece, incredible weather, very interesting culture. Kids loved it, we loved it. I felt it was much better value for money and much more 'us' than Sani which we would never go to if we hadn't had the kids.
That said, people love Sani. Our friends certainly do. It's all very subjective isn't it
