Vista badia, Sa Coma Majorca, been twice.
Safari next door has an even bigger pool, but is huge.
My older DDs like to buzz of to the pool and find a sun bed and I don't think I'd ever find them there.
Complex has a water park that would suit that age (my mob do huge water slides so it's a trip to Palma).
Sa Coma is a lovely, safe beach and you can stroll down into S'Illiot.
We went with Thompson. The Bonaire in Cala Bona is beautiful, huge pool. More of a hike to the beach.
Fiesta Palm Beach, Ibiza.
Lovely hotel, nice pool and plenty of shady sun lounges. Very good food. Gardens open on to the beach (fence and gate, so safe for children).
Downsides you need a bus into town only a few shops and big space club near by.
Water park walk able, but not much for small DCs. They were enforcing the hight limit so 5 might be very frustrated.
Under flight path for airport. We thought this was great and my DCs enjoyed plain sporting.
Not apartments, don't know what they do for family rooms.
We booked late, got two ordinary twins and ignored being told that we needed an adult in each. (DDs are 14 and 11)
