We went the first two weeks in July with 3 kids, 8,6 and 3. We booked it direct with the hotel rather than through a company and booked the flights directly.
I read the internet and the reviews were very mixed, they either loved it or hated it and nothing in between. For us it was fine, we stayed in Leda 3 and the room was clean and it was quiet in the evening. The main problem with the room was the lack of air con but you could hire fans for the week for a refundable deposit which were fine. The pool at Leda 3 was cleaned every night and the all inclusive bar was fine with no queue for soft drinks and a small queue at busy times for alcohol.
The food was served in a main dining room which at times was busy but there was loads of choice and unlike some people on the review I didn't have chips with every meal. the best bits were the majorcan food and the variety of salads that you could have. Some people thought the food was limited but my kids enjoyed it and liked the fact they could have what they wanted and could try what they wanted.
The evening entertainment was OK, a kids show followed by a set of tribute bands or shows. The tribute bands were fine, Take that being the best but the shows were a bit dire. The beach is great and if you take the boat from the hotel it takes you to a quiet part of the beach. You can take the boat there and walk back via the town. We did a couple of tours and they were fine but we wished we had spent some more thime in the town when we had the chance, the old part is beautiful.
I would say its fine for sleeping and eating in but bear in mind its not a five star hotel by any means but the kids loved it and we would go back. I am a bit of a hotel snob but where we were it was clean, quiet and just what we needed.
